What has been known in Kabbalah since the 15th century as the "Tree of Life" is but its outer form. The two sets of seven enfolded, regular polygons constitute its inner form. The picture shows the outer form projected onto the plane containing the 14 polygons. It also depicts a column of four white circles overlapping centre-to-circumference. Two white circles are centred on two of their points of intersection, which coincide with Chesed and Geburah. The non-Sephirah Daath (dashed circle) and the Sephiroth Chesed, Geburah & Tiphareth project onto the boundary of a Vesica Piscis in the plane of the 14 enfolded polygons. It encloses the two violet triangles that are part of the inner Tree of Life.
