A corner of each triangle in the inner Tree of Life is the centre of a hexagon. A corner of each pentagon is the centre of the decagon. This means that only five of the seven centres of each set of polygons are independent, for the two other centres in each set are part of polygons. The outer Tree of Life essentially consists of 10 points (the Sephiroth) and the point at which the non-Sephirah 'Daath' is located. The outer and inner Trees of Life therefore comprise, respectively, (10+1) points and (5+5) points, i.e., 21 points. This is the number value of EHYEH (Hebrew: AHIH), the Godname of Kether. The numbers 1, 5, 10 & 5 denote the respective values of the letters A, H, I & H making up the Hebrew word for this Divine Name.
