Revered by Hindus as the most sacred of the yantras, the Sri
Yantra is said to represent the process of unfolding of Divine Creation. This
article confirms their belief by correlating the Sri Yantra with the Tree of
Life. The first three layers of triangles have 168 geometrical elements
comprising 84 edges and 84 vertices & triangles. As discussed in many
previous articles, this number is the structural parameter of the
E8×E8 heterotic superstring. The numbers of different
types of edges and vertices in these layers are exactly the same as the numbers
of various types of non-zero roots making up the 168 non-zero roots of the
superstring gauge symmetry group E8 that do not belong to its
subgroup E6.The 48 geometrical elements in the first layer of
triangles consist of eight groups of six geometrical elements. This 8×6 pattern
has parallels in many other holistic systems discussed in previous articles. The
Sri Yantra has 260 geometrical elements, showing how it is prescribed by the
Godname YAHWEH, whose gematria number value is 26. There are 260 geometrical
elements in the seven overlapping Trees of Life that map the seven planes of
consciousness. The Sri Yantra is also equivalent to the inner form of the Tree
of Life, which has 260 yods outside its root edge when the sectors of its seven
polygons are tetractyses. When each is divided into three triangles, the 14
triangles of the fourth layer have 168 geometrical elements and the 28 triangles
of the first three layers have 336 elements. These numbers are the numbers of
circularly polarised oscillations in, respectively, a half-revolution and a
whole revolution of each curve making up the E8×E8
heterotic superstring. They correspond to the 168 automorphisms of the Klein
Quartic and to its 336 automorphisms and anti-automorphisms. There are also 336
yods on the edges of the 42 triangles in the four layers. The 70 vertices of the
2-d Sri Yantra correspond to the 70 yods of the outer Tree of Life constructed
from tetractyses. The 236 geometrical elements making up the four layers
correspond to the 236 yods on the boundaries of the 14 polygons in the inner
Tree of Life. The 2-d Sri Yantra is equivalent to the disdyakis triacontahedron
with 362 geometrical elements in its faces because its four layers of triangles
have 362 yods. The 8:6 division of tips of triangles in the fourth layer
reflects the eight Pythagorean and six non-Pythagorean notes in the seven
musical scales. The numbers in Plato’s Lambda appear within in the Sri Yantra in
its nine basic triangles regarded as tetractyses. The seven positive and seven
negative points of these Shiva and Shakti triangles symbolize the seven Yang and
the seven Yin acupuncture meridians. They also signify the seven notes and their
complements that make up the seven musical scales.
1. Sri Yantra
The Sri Yantra (Fig. 1) is revered by Hindus as the most powerful and sacred of the yantras,
or images used for meditation. Five downward pointing triangles that symbolize the feminine
creative energy, or Shakti, intersect four upward-pointing triangles symbolizing
the masculine creative energy, or Shiva. This generates 42 triangles
arranged in four layers of eight, 10, 10 and 14 triangles. They surround a downward pointing
triangle whose corners denote the triple Godhead of Shiva, Brahma and Vishnu. At its centre is
a point, or bindu, representing the Absolute. Table 1 shows the numbers of vertices, edges and triangles in the Sri

The Sephiroth exist in the four Worlds of Atziluth, Beriah, Yetzirah and
Assiyah. Corresponding to them are the Godnames, Archangels, Order of
Angels and Mundane Chakras (their physical manifestation). This table gives
their number values obtained by the ancient practice of gematria, wherein a
number is assigned to each letter of the alphabet, thereby giving a number
value to a word that is the sum of the numbers of its letters. All numbers
in the table that appear in the article are written in
The 42 triangles in the four levels have 84 vertices and 126 edges. The
Godname EHYEH (see Table 2) prescribes the number of triangles because 42 is the
21st even integer. It prescribes the number of edges because 126 is the sum
of the values of all the possible combinations of the three letters A, H & I in
A = 1, H = 5, I = 10
||A + H + I
||AH + HI + AI + HH
||AHI + HIH + AHH
The number of vertices is 84, where
84 = 12 + 32 + 52 + 72.
The number of geometrical elements is 252, which is the 126th even
The first three levels have 84 edges, 56 vertices and 28 triangles, that is,
84 vertices and triangles, totalling 168 geometrical elements. This equal
84:84 division of the number value 168 of Cholem Yesodeth, Mundane
Chakra of Malkuth, has been encountered in many previous articles. Examples are:
1. Article 15,1 which discussed the 84 permutations of pairs and triplets of
octonions belonging to the seven 3-tuples of octonions (ei, ei+1,
ei+3) and the 84 permutations of their inverses;
2. Article 18,2 which discussed the I Ching table of 64
hexagrams and the 28 hexagrams on either side of its diagonal. Each hexagram is a pair of
trigrams, so that each set of 28 off-diagonal hexagrams has (28×2×3=168)
lines and broken lines. Each set comprises 84 lines and 84 broken lines;
3. Article 21,3 which discussed the 84 hyperbolic triangles in each of the two
types of seven similar slices of the Klein Configuration, the diagram whose
168 hyperbolic triangles represent the 168 automorphisms
of the equation known to mathematicians as the Klein Quartic;
4. Article 16,4 which discussed, firstly, the 84 repetitions of the
Pythagorean-valued, rising intervals between the notes of the seven types of musical scales
and their 84 falling intervals (pp. 17–18), and, secondly, the 84 yods belonging to the
first four enfolded polygons enfolded in each half of the inner Tree of Life that either are
not centres of polygons or do not coincide with Sephiroth (pp. 23–24).
5. Article 33,5 which found that the lowest five of the seven polygons formed by
vertices of the disdyakis triacontahedron have 84 vertices & triangles and 84 edges.
The 84:84 division is an indication that the Sri Yantra constitutes sacred
geometry that is isomorphic to other systems of sacred geometry. This conclusion is
confirmed by the fact that, together with the eight geometrical elements in
the central triangle and bindu, the Sri Yantra has 260 geometrical elements. This is the
number of yods outside the root edge of the seven enfolded polygons making up the inner form
of the Tree of Life when their 47 sectors are turned into tetractyses (Fig. 2). The Godname YAHWEH with number value 26, which
expresses the creative power of God, prescribes how many geometrical elements the Sri Yantra
The 168 elements of the first three layers comprise 56
vertices, 84 edges and 28 triangles. The 56 vertices consist of 28 that form the bases of
the triangles and 28 that are their apices. The 84 edges consist of 28 that are bases of
outward pointing triangles and 28 pairs of edges forming their points. Hence, the
composition of the 168 elements is:
56 vertices = 28 base vertices + 28 apices
28 base edges
Compare this with the forms of the 8-tuples and their numbers representing
the 168 nonzero roots of the superstring gauge symmetry group E8
that are not also non-zero roots of its exceptional subgroup E6:
We find that the numbers of types of geometrical elements making up the
first three layers of the Sri Yantra are the same as the numbers of different 8-tuples of
non-zero roots belonging to E8 but not to E6. The geometry of the 28
triangles in these three layers is analogous to the permutations of 8-tuples representing
these non-zero roots!
The 43 triangles have 129 edges, where 129
is the number value of YAHWEH SABAOTH, Godname of Netzach. The innermost triangle consists
of two edges that meet at the middle of an edge of the lowest triangle of the fourth layer
and one edge that joins
vertices of triangles in that layer, which is composed of 24 edges. The 27
edges of the central triangle and first layer therefore divide into (26+1)
edges. This means that the 129 edges consist of 26 edges
of the central triangle and first layer and 103 edges of the central
triangle and other three layers. 26 is the number value of YAHWEH and
103 is the number value of SABAOTH.
The first layer has 48 geometrical elements consisting of
eight pairs of vertices, eight triplets of edges and eight triangles, that is, eight
groups of six elements. 48 is the number value of Kokab, the Mundane Chakra of Hod. The third & fourth layers
of triangles have
48 vertices and the first & second layers have
36 vertices (Fig. 3). They correspond to the 48 yods up to Chesed of the
1-tree and the 36 yods above it. The seven separate polygons in the inner
Tree of Life have 48 corners and seven centres (Fig. 4). These correspond to the 48 elements of the first
layer of triangles and to the seven elements of the central triangles.
The bindu point at the centre of the Sri Yantra is surrounded by
87 vertices of 43 triangles with 129 edges, that is, by
(87+129=216) vertices and edges.
216 is the number value of Geburah and 87 is the edges and
126 vertices and triangles in the four layers of
triangles surround number value of Levanah, the Mundane Chakra of
Yesod. 126 the bindu. Including the innermost triangle, the 260 geometrical elements are
made up of 126 edges of the four layers of triangles and 134 geometrical elements made up of
88 vertices, three edges and 43 triangles. This 126:134 division is reflected in the 260
yods outside the root edge of the seven enfolded polygons as the 126 yods in the decagon and
dodecagon and as the 134 yods in the first five polygons (Fig. 5). It is further confirmation of the Tree of Life nature of the Sri
Yantra. Corresponding to its 88 vertices and 129 edges are the 88 edges of
the 47 sectors of the seven enfolded polygons in the inner Tree of Life and their
129 vertices and edges.
2. Sri Yantra
with triangles divided into sectors
Suppose that each triangle in the Sri Yantra is divided into its sectors.
Table 3 below displays the numbers of resulting vertices, edges & triangles.
Table 3. Geometrical composition of the 3-d Sri
There are 131 vertices, where 131 is the
number value of Samael, the Archangel of Geburah. This property is prescribed by the
Godname ADONAI with number 65 because 131 is the
65th odd integer after 1. Below the bindu are 130 vertices. Whereas there
are 126 edges in the four layers of triangles when the latter are single tetractyses, there
are 126 vertices when the triangles are constructed from three tetractyses. There are also
126 triangles. The Godname YAHWEH SABAOTH with number value 129 prescribes
the 129 triangles and the 130 vertices because 130 is the
129th integer after 1.
According to Table 3, the fourth layer of triangles has 168 geometrical
elements made up of 84 edges and 84 vertices and triangles. Compare this with its 84
elements when the triangles are single tetractyses and with the 168
elements of the first three layers. What
was in the latter now appears in the fourth when the triangles are divided
into three. The first three layers have 336 elements made up of 168 edges
and 168 vertices and triangles. This
168:168 division appears in
the Klein Configuration as the 168 hyperbolic triangles
representing the 168 automorphisms of the Klein Quartic and the
168 triangles representing its 168
anti-automorphisms.6 As discussed in many previous articles, it appears in the
E8×E8 heterotic superstring as the
168 circularly polarised oscillations made in half a
revolution of each of its ten curves, the 168:168 division reflecting the
distinction between the outer and the inner halves of each curve (Fig. 7). It appears in the disdyakis triacontahedron as the
168 geometrical elements in its faces above the central layer of vertices
and their 168 mirror-image elements in its faces below it.7
The four layers of triangles have 504 geometrical elements made up of
168 elements in the fourth layer and 336 elements in the first three layers
(168 edges and 168 vertices and triangles). This
168:168:168 composition manifests (apart from the Tree of Life factor of
10) in the heterotic superstring as the 1680 oscillations in each of the three major whorls
(the thicker whorls shown in Fig. 7). The geometry of the Sri Yantra encodes that
Table 4. Geometrical composition of the 2-d Sri Yantra.
part of the superstring that is the counterpart of the Supernal Triad of
Kether, Chokmah and Binah, or Shiva, Brahma and Vishnu. The counterpart of the 504
geometrical elements in its four layers of triangles is the 504 oscillations in half a
revolution of its three major whorls.
If the triangles are divided into three triangles and then each of the
latter is three triangles, it is found that the four layers of triangles have 252 vertices,
630 edges and 378 triangles, totalling 1260 geometrical
elements. This is the number value of Tarshishim, the Order of Angels assigned to
If the 3-dimensional Sri Yantra is projected onto a sheet, the numbers of
edges and triangles are unchanged but the number of vertices is reduced (Table 4). As before, the fourth layer has 28 vertices. The third layer has 12
vertices instead of 20 vertices, the second layer has 16 vertices instead of 20 vertices
and the first layer has 12 vertices instead of 16. The projection of
the four layers now comprises 68 vertices instead of 84, that is, 16
fewer vertices. The innermost triangle adds one vertex. Including the bindu, the
projected Sri Yantra therefore has (1+1+68=70) vertices. This is the number
of yods in the Tree of Life when its 16 triangles are turned into tetractyses (Fig. 8). It is also the number of corners of the two sets of seven enfolded
polygons. The two ends of the root edge correspond to the bindu and the lowest vertex of the
central triangle. In each case, the two points do not shape the holistic structure because
they represent its seed source, in the latter case the bindu being an isolated point and the
lowest vertex being not at a corner of a triangle but at the midpoint of the edge of one.
The 68 vertices of the four layers of triangles correspond to the 68 corners of the 14
polygons outside their shared root edge.
Instead of having 252 geometrical elements (see Table 1), the four layers of triangles now have 16 fewer, i.e., 236 elements.
This is the number of yods on the boundaries of both sets of seven enfolded polygons
(Fig. 9). As in the 3-dimensional case, the four layers of triangles in the
2-dimensional Sri Yantra have 126 edges of 42 triangles. Now, however, it has
(68+126+42=236) geometrical elements. The central triangle adds one vertex and three edges
but not a triangular area because it has a point at its centre. Including this bindu, the
2-dimensional Sri Yantra has (236+1+3+1=241) geometrical elements. In other words, 240
geometrical elements surround the bindu. 168 of these are either edges or
triangles (see Table 1) and the remaining 72 elements consist of the 68
vertices of the 42 triangles, the single vertex of the central triangle unshared with other
triangles, its three edges and the bindu. This property is remarkable because the division:
240 = 72 + 168 corresponds in the superstring gauge
symmetry group E8 to the 72
non-zero roots of E6 and the remaining 168
non-zero roots of E8. The geometrical composition of the 2-dimensional Sri Yantra
therefore reflects the root composition of E8 and its subgroup E6.
Seven overlapping Trees of Life have 47 Sephirothic emanations (called
“Sephirothic levels,” or SLs). There are 43 SLs up to Chesed of the seventh tree, the
formative, starting point of the emanation of the seven Sephiroth of Construction, each
mapped by a tree. This is the number of triangles in the Sri Yantra
(Fig. 10). Each triangle symbolizes one of the seven-fold
differentiations of the seven Sephiroth of Construction. Each tree maps one of the seven
planes of consciousness: in Theosphical terms, the physical, astral,
mental, buddhic, atmic, anupadaka and adi plane. As all the spiritual realms
as varieties of consciousness symbolized by triangles emerge from the Absolute symbolized by
the bindu, so successive SLs emanate from the Supernal Triad of the highest tree. The
central triangle symbolizes the commencement of ‘objective’ existence — not in a physical
sense but in the metaphysical sense of separation from the subjective unity of God
symbolized by the bindu point of the Sri Yantra and by the Supernal Triad at the top of the
first Tree of Life.
Spectacular confirmation that the Sri Yantra is equivalent to seven
overlapping Trees of Life comes from considering the geometrical composition of a set of n
Number of vertices of triangles ≡ S(n) = 6n + 4.
Number of edges of triangles ≡ E(n) = 16n + 6.
Number of triangles ≡ T(n) = 12n + 4.
Number of tetrahedra ≡ t(n) = n + 1.
Number of geometrical elements in n Trees of Life = S(n) + E(n) + T(n) +
t(n) = 35n + 15. Hence, seven Trees of Life have 260 geometrical elements
made up of 46 vertices (S(7)), 118 edges (E(7)), 88 triangles (T(7)) and eight tetrahedra
(t(7)). Compare this with the
composition of the Sri Yantra indicated in Table 1: 260 geometrical elements comprising 88 vertices,
129 edges and 43 triangles. Amazingly, both the Sri Yantra and seven Trees
of Life have the same number of geometrical elements! The latter has 252 vertices, edges and
triangles — the same number that the four layers of triangles have. The eight elements
possessed by the bindu and innermost triangle correspond to the eight tetrahedra in the
seven Trees of Life. The number 88 applies to vertices in the Sri Yantra and to triangles in
the seven Trees of Life. What is so significant here is not only that both structures have
the same number of geometrical elements but also that this number is 260 — the number
of yods in 26 tetractyses and the number of yods needed to construct the
inner form of the Tree of Life, starting from the root edge (see Fig. 5). This is additional evidence that the Sri Yantra represents the seven
Trees of Life mapping the seven planes of consciousness.
In my book “The Mathematical Connection between Religion and
Science,”8 I showed how, when considered separately, the seven polygons
making up the inner Tree of Life have, when constructed from tetractyses, as many yods as
there are SLs up to the first Sephirah of Construction of the 49th Tree. In
other words, the seven enfolded polygons encode seven overlapping Trees and the seven
separate polygons encode 49 overlapping Trees. Each plane of consciousness
mapped by a Tree of Life has seven subplanes that, too, can be mapped by a Tree of Life,
making (7×7=49) Trees. The Sri Yantra is a map of the seven planes of
consciousness that can be mapped both by seven Trees and by 49 Trees. The
latter is simply the seven-fold differentiation of the former.
composition of the Sri Yantra
Suppose that each of the 43 triangles in the Sri Yantra is turned into a
tetractys. Table 5 shows the numbers of yods in each layer.
Table 5. Yod population of the 3-d Sri Yantra (triangles as tetractyses).
The four layers of triangles have 378 yods, of which (378–42=336) yods lie
along their 126 edges. The latter yods are made up of 84 vertices, 84 hexagonal yods on the
42 edges of the fourth layer and 168 hexagonal yods on the 84 edges of the
first three layers. Once again, we encounter the superstring structural parameters 84,
168 and 336. The number 336 is the number of yods needed to form the
boundaries of all 42 triangles in the four layers. It has the same 168:168
division as found earlier for the geometrical elements composing the first three layers of
triangles. The number 336 defines the shapes of the triangles in the four layers, confirming
its shape-defining character vis-à-vis the heterotic superstring as the number of times each
of its ten curves oscillates during one complete revolution as it spirals around its spin
axis. This result is very satisfying, for it not only confirms the validity of Besant’s and
Leadbeater’s account of superstrings over a century ago but confirms the nature of the Sri
Yantra as the blueprint for matter.
The number of yods on the edges of the 14 triangles is 112.
This is the number value of Beni Elohim (“Sons of God”), the Order of Angels assigned
to Hod. The first layer of triangles has 64 such yods, 48
being hexagonal ones. 48 is the number value of Kokab, the Mundane
Chakra of Hod. 64 is the number value of Nogah, the Mundane Chakra
of Netzach, the Sephirah preceding Hod in the Tree of Life. There are 87
corners of the 43 triangles. 87 is the number value of Levanah,
Mundane Chakra of Yesod. 168 — the number of edges and triangles in the
four layers — is the number value of Cholem Yesodeth, the Mundane Chakra of Malkuth.
This demonstrates how the number values of the Mundane Chakras of the last four Sephiroth
define properties of the Sri Yantra.
Now consider each triangle constructed from three tetractyses. Table 6 displays the number of yods in each layer.
Table 6. Yod population of the 3-d Sri Yantra (triangles as three
There are 776 yods, of which 88 yods are vertices of the Sri Yantra before
it is constructed from tetractyses. (776–88=688) extra yods are needed to build it. The
fourth layer of 14 triangles has 210 yods on their boundaries, showing how the Godname EHYEH
with number value 21 prescribes the last layer. Suppose, however, that we
regard the central triangle as not transformable into a tetractys or three tetractyses
because it signifies the triple Godhead. As before, there are 88 vertices, but now there are
252 hexagonal yods on the edges and 420 yods inside triangles, totalling 760 yods. The
Godname YAHWEH ELOHIM (“God the Creator”) with number value 76 prescribes
the number of yods needed to construct the Sri Yantra because it can be built from the yods
in 76 tetractyses — further evidence that it represents the creative design
The number of vertices of the 126 tetractyses in the four layers of 42
triangles = 84 + 42 = 126. The bindu and central triangle (undivided into tetractyses) have
four vertices, so that the Sri Yantra has 130 vertices. This is the 65th
even integer, showing how ADONAI with number value 65 prescribes the form
of the Sri Yantra. It illustrates the shape-defining nature of this Godname of
Malkuth, the Sephirah signifying the ‘body’ of Adam Kadmon, or the outer form of the Tree of
The 42 triangles in the four layers have 756 yods, that is, (756–84=672)
yods other than their 84 vertices. Their 126 tetractyses have 126 vertices and
(756–126=630) hexagonal yods. As each triangle has nine hexagonal inside
it, there are (9×42=378) hexagonal yods inside the triangles and 252 hexagonal yods on their
edges. Table 5 indicates that the first three layers of 28 triangles have
168 hexagonal yods on their 84 edges and 280 yods inside
them. 280 is the number value of Sandalphon, the Archangel of
Mundane Chakra has the number value 168. This conjunction
of two numbers belonging to the same Sephirah illustrates how Godnames, Archangelic Names,
etc collectively define an object like the Sri Yantra that embodies the divine
Let us next consider the projection of the Sri Yantra onto a sheet. Firstly,
we will analyse the case where the triangles are single tetractyses. Table 7 lists the numbers of yods.
Table 7. Yod population of the 2-d Sri Yantra (triangles as tetractyses).
The 84 vertices of the 42 triangles now become 68 vertices, i.e., 16 fewer.
The four layers of triangles now have 362 yods instead of 378 yods. This is the number of
than corners of polygons needed to create the edges of the 94 tetractyses in
both sets of seven polygons in the inner Tree of Life (Fig. 10). 362 is also the number of yods in the two dodecagons when their 24
sectors are divided into three tetractyses (Fig. 11). Most
significant of all, it is the number of geometrical elements making up
the faces of the disdyakis triacontahedron, which has 62 vertices, 180
edges and 120 triangular faces. This connects the Sri Yantra with this polyhedron, for both
are parameterized by the
same number of bits of information — yods or geometrical elements.
Consider next the 2-d Sri Yantra with their
triangles constructed from three tetractyses. Table 7 indicates that, Instead of 756 yods (see Table 6), the 42 triangles now regarded as in one layer have 740
yods. Instead of 630 boundary yods, they have 614 yods. The
Table 8. Yod composition of the 2-d Sri Yantra (triangles as three
number of yods other than the 68 vertices of triangles is 672. If the
central triangle is divided into three tetractyses, it has 15 yods other
than vertices. The 2-dimensional Sri Yantra therefore has (672+15=687) yods
other than vertices. 687 extra yods are needed to construct each of its 43 triangles from
three tetractyses. Amazingly, the seven enfolded polygons of the inner Tree of Life have 687
yods! (Fig. 13).
Constructed from three tetractyses, the 42 triangles surrounding the central
one have 740 yods that comprise 110 vertices (68 vertices of triangles) and
630 hexagonal yods. The total number of vertices is 112.
This is the number value of Beni Elohim, the Order of Angels assigned to Hod. The
fourth set of triangles has 252 yods (42 vertices & 210 hexagonal yods). 42 hexagonal
yods are centres of the 42 tetractyses, leaving (210–42=168) hexagonal yods
lining the edges of these tetractyses. The superstring structural parameter
168 defines the shape of the 42 tetractyses in the 14 triangles, showing
how superstring structure is embodied in the Sri Yantra.
4. The Sri Yantra defines the seven musical
As shown in Article 14,9 the seven types of musical scales have 14 different notes
with tone ratios:
1 256/243 9/8
32/27 81/64 4/3
3/2 128/81 27/16
16/9 243/128 2
(Numbers in red denote notes not belonging to the Pythagorean scale
(C-scale). Including the tonic, they consist of seven pairs that, as intervals, span an
octave. In order of increasing pitch, they are:
1×2 = 2
256/243×243/128 = 2
9/8×16/9 = 2
32/27×27/16 = 2
81/64×128/81 = 2
4/3×3/2 = 2
1024/729×729/512 = 2
The seven notes in the first column consist of four Pythagorean notes and
three non-Pythagorean notes; similarly for their complements in the second column. The 14
notes therefore consist of eight Pythagorean notes and six non-Pythagorean notes.
Compare this division of types of notes in the seven musical scales with
pattern of triangles in the first layer of the Sri Yantra. Each of the seven triangles in
the upper half has its counterpart in the lower half (not every pair, however, is,
literally, a pair of mirror images, for only the four triangles joined across the central,
horizontal line are identical).
Six of the 14 triangles touch the circumscribing circle. They can be thought
of as corresponding to the six non-Pythagorean notes, whilst the eight triangles whose
apices do not touch the circle correspond to the eight Pythagorean notes (Fig. 14). Each note assigned to the point of a triangle has a complement
assigned to the point that is its mirror image. The pattern of the fourth layer of triangles
differentiates between not only the notes and their complementary partners but also the
Pythagorean and non-Pythagorean notes!
5. Connection between the Sri Yantra and Plato’s
According to Plato, the demiurge measured the World Soul with
the harmonic proportions of the Pythagorean musical scale by taking a strip of it and
dividing its length into portions measured by the first four numbers of the two geometric
series: 1, 2, 4, 8, …and 1, 3, 9, 27, … . However, these seven numbers are but members of
a tetractys array of ten numbers (Fig. 16) whose ratios define the tone ratios of the notes of the Pythagorean
scale.10 Their sum is 90, the sum of the integers at the corners
of the tetractys is 36, the
sum of the seven integers arranged at the centre and corners of a hexagon
(shown in Fig. 15 by dashed lines) is 54 and the sum of the integers forming the
hexagon is 48. These numbers define the tone ratio 3/2 of the perfect fifth
because 54/36 = 3/2 and the tone ratio 4/3 of the perfect fourth because
48/36 = 4/3.
The Sri Yantra is formed by the intersection of nine triangles. Let us
regard each triangle as a tetractys. The nine tetractyses have 90 yods, of which
36 are corners or centres and 54 are hexagonal yods surrounding their
centres. The 36:54 division of yods corresponds to the two sums of numbers
at the corners of the Lambda tetractys and at the centre and
corners of the hexagon. The sum of the nine integers surrounding the central
one in the Lambda tetractys is 84. According to Table 1, this is the number of vertices of the 42 triangles formed by the
intersection of the nine triangles. Moreover, the first and second layers have
36 vertices and the third and fourth layers have 48
vertices. The former is the sum of the numbers at the corners of the Lambda tetractys and
the latter is the sum of the numbers arranged in a hexagon. The first two layers therefore
are the counterpart of the corners of the Lambda tetractys and the last two layers are the
counterpart of the hexagonal array of six integers.
42 of the 84 vertices are the tips of the 42 triangles and the other 42
vertices are points where triangles join. The 42:42 division of vertices has its counterpart
in the Lambda tetractys as the sums of the two pairs of diagonal rows of numbers:
1+2+4+8+27 = 42,
3+12+9+18 = 42.
These correspondences demonstrate that the Lambda tetractys is
arithmetically equivalent to the Sri Yantra. The reason for this is that the former is an
archetypal array of numbers that generate by combination the properties of the Tree of
The 36:54 division was found11 in the disdyakis triacontahedron as the 360 tetractyses needed
to construct each of its 120 triangular faces from three tetractyses and the 540 internal
tetractyses needed to construct the 180 interior triangles formed by its 180 edges when each
is built from three tetractyses.
A tetractys defines the Sri Yantra in another way. The number 84 is the sum
of the squares of the first four odd integers:
84 = 12 + 32 + 52 + 72.
12 = 1
32 = 1 + 3 + 5
52 = 1 + 3 + 5 + 7 + 9
72 = 1 + 3 + 5 + 7 + 9 + 11 + 13,
84 = 4(1) + 3(3+5) + 2(7+9) + 1(11+13) = 4×1 + 3×8 + 2×16 + 1×24
8 8 8
1 1 1
84 is naturally expressed as a tetractys array of 10 integers. Moreover, the
central integer 8 denotes the innermost eight vertices of the first layer of triangles and
the nine surrounding integers add up to 76, which is the number of vertices
surrounding them. 76 is the number value of YAHWEH ELOHIM, Godname of
Tiphareth, the centre of the Tree of Life. The number value 26 of YAHWEH is
the sum of the integers at the corners of the tetractys and the number value
50 of ELOHIM is the sum of the six integers arranged in a hexagon. This is
a remarkable conjunction of sacred geometry and number. The sum of either diagonal row of
integers is 49, which is the number value of EL CHAI, the Godname of
The successive differentiations of divine unity are symbolised by the point,
or Pythagorean Monad (0th-order tetractys), the 1st-order tetractys, the 2nd-order
tetractys, etc. The next higher order tetractys after Pythagoras’s well-known one is the
2nd-order tetractys (Fig. 16) with 85 yods, where
85 = 40 + 41 + 42 + 43.
84 yods surround its centre. 36 yods lie on its boundary and
49 yods lie inside it, 48 of them surrounding its centre
this with the fact that the first two layers of
triangles in the Sri Yantra have 36 vertices and the last
two layers have 48 vertices. The Sri Yantra is equivalent to the 2nd-order
The number of yods in an n-sided polygon whose n sectors are tetractyses is
6n + 1. The tips of the 14 triangles in the fourth layer of the Sri Yantra may be regarded
as defining the vertices of a 14-sided polygon (not regular). It contains (6×14 + 1 = 85)
yods (Fig. 18). 84 yods surround its centre. The 85 yods comprise 70 hexagonal
yods and 15 vertices. This is identical to the pattern of 70 hexagonal yods
and 15 vertices in the 2nd-order tetractys. Not only is the whole Sri
Yantra equivalent therefore to a 2nd-order tetractys but also the 14-sided polygon marked
out by the tips of the 14 triangles in the last layer! Wholeness within wholeness.
The yod populations of the four polygons whose vertices are the tips of
triangles are shown below:
Number of hexagonal yods
Number of yods
1st layer: 8-sided polygon
2nd layer: 10-sided polygon
3rd layer: 10-sided polygon
4th layer: 14-sided polygon
The total number of yods needed to construct the 42 tetractyses in the four
polygons is 256 = 44. This is a remarkable illustration of the Tetrad Principle
governing holistic patterns.12 The Godname EHYEH with number value 21
prescribes the number of hexagonal yods. The number of yods surrounding the centres of the
polygons in the first three layers is 168 and the number surrounding the
centre of the 14-sided polygon is 84. It is remarkable that both these superstring
structural parameters are embodied in the four polygons. What more convincing evidence that
the Sri Yantra encodes the physics of superstrings could one ask for?
When their sectors are divided into three tetractyses, the yod populations
of the four polygons are:
Number of hexagonal yods
Number of yods
1st layer: 8-sided polygon
2nd layer: 10-sided polygon
3rd layer: 10-sided polygon
4th layer: 14-sided polygon
There are 630 yods surrounding the centres of the polygons.
630 is the number value of Seraphim, the Order of Angels assigned to
Geburah. In the 2-dimensional Sri Yantra, all the centres coincide, so that
630 yods surround their common centre. The number of yods needed to create
the four layers of triangles other than their outermost 14 tips is
(634–14=620). This is the number value of Kether (“Crown”).
The four polygons have 546 hexagonal yods. Of these, 126 are centres of 126
tetractyses, leaving 420 hexagonal yods on 210 edges. Including their 88 vertices, there are
508 yods on the edges of the tetractyses. In the 2-dimensional Sri Yantra, 16 vertices of
the four polygons merge with other vertices and three centres merge with the fourth, leaving
(508–19=489) yods. There are (489–15=474) yods other than
the centre and the 14 vertices of the outermost polygon. This is the number value of Daath
(“knowledge). It is the number of yods, starting with the bindu, needed to delineate the
shapes of the
tetractyses composing the 2-dimensional Sri Yantra until the vertices of the
last polygon are left.
As Table 9 shows, 474 geometrical elements are needed to
construct the four sets of triangles in the 2-d Sri Yantra until its outermost tips are
Table 9. Geometrical composition of the 2-d Sri Yantra (triangles as three
The four sets of triangles have 488 geometrical elements, that is,
(488–14=474) elements other than the 14 outermost tips of the triangles in
the fourth layer. Including the central triangle and the bindu point, the 2-dimensional Sri
Yantra has 499 elements. Suppose, however, that the central triangle and bindu are regarded
as floating above the planar group of 42 triangles. Instead of adding one vertex according
to Table 9, the former would add three vertices because its two other corners no
longer coincide with corners of the innermost group of eight triangles, so that 500
(=50×10) elements surround the bindu. This shows in a remarkable way the
in which ELOHIM, the Godname of Binah with number value 50,
determines the geometrical composition of the Sri Yantra. The justification for treating the
central triangle and bindu as outside the plane of the triangles would be that they
symbolize the Absolute and the triple Godhead, which stand outside of Creation represented
by the rest of the yantra.
Returning to the discussion of the polygons formed by vertices of triangles,
there are 489 yods on edges of tetractyses in the 2-dimensional Sri Yantra, i.e., 488
boundary yods surround the bindu. If the central triangle is constructed from three
are (488+12=500=50×10) boundary yods other than the bindu
and the corners of the triangle symbolizing the triple Godhead. This shows how ELOHIM with
number value 50 prescribes the population of yods that shape the
2-dimensional Sri Yantra.
6. The Sri Yantra defines the
Seven triangles in the fourth layer of
the Sri Yantra are tips of three downward pointing triangles said by Hindus to represent
the ‘Shakti (female) energy of creation. Seven triangles are tips of upward pointing
triangles that represent the ‘Shiva’ (male) procreative energy. Seven tips therefore have
a positive polarity and seven have a negative polarity. The seven pairs of positive and
negative tips have its counterpart in the fourth (and last) class of numbers known as
the octonions, or Cayley numbers. The former correspond to
the seven imaginary octonions ei (i = 1–7) and the latter
correspond to their conjugates ei* = –ei, where
eiei* = 1 (Fig. 19). The seven imaginary octonions form seven 3-tuples (ei,
ei+1, ei+3), each having six permutations of pairs and six
permutations of all three. This means that the seven 3-tuples have (7×6=42) permutations of
pairs and 42 permutations of three octonions.13 This is symbolized in the Sri Yantra as the 42 vertices formed
by the convergence or intersection of two edges of the nine triangles and the 42 vertices
created by the intersection of three edges, as the following table of numbers of vertices
Layer 1: 8 triangles
Layer 2: 10 triangles
Layer 3: 10 triangles
Layer 4: 14 triangles
A vertex formed by the convergence or intersection of two edges symbolizes a
permutation of two imaginary octonions and a vertex formed by the intersection of three
edges symbolizes a permutation of three octonions. This has significant
implications that will not be pursued here.
7. The Sri
Yantra defines the 12 acupuncture meridians
The five downward triangles symbolize the feminine (Shakti) energies of
creation and the four upward triangles symbolize the male (Shiva) energies. In Taoist
philosophy, they are the Yin and Yang polarities. Another interpretation of the seven positive,
or Yang, polarities and seven negative, or Yin, polarities associated with the tips of the
triangles in the fourth layer is that the former symbolize the seven Yang meridians and the
latter symbolize the seven Yin meridians known in Chinese acupuncture.14 The upper part of the human body has three Yang hand
meridians, three Yin hand meridians, the Governing Vessel,
which is Yang, and the Conception Vessel, which is Yin
(Fig. 20). The lower half of the body has three Yang foot meridians and three
Yin foot meridians. The upper
and lower halves of the body therefore divide the 14 meridians into eight
that belong to the former and six that belong to the latter. As with the seven musical
scales, the 8:6 division appears in the meridians. The eight triangles of the fourth layer
whose tips do not touch the circumscribing circle symbolize the eight meridians in the upper
part of the body and the six triangles whose tips touch the circle represent the six foot
meridians (Fig. 21). Notice that these triangles are the tips of two intersecting Shiva
and Shakti triangles forming a Star of David or Sign of Vishnu. This corresponds to the
three Yang foot meridians (Stomach, Gall Bladder and Bladder) and to the three Yin foot
meridians (Spleen, Kidney and Liver).
