Converted into tetractyses, the 16 triangles of the outer Tree of Life contain 70 yods. Just as the measure of human life is 70 years, according to Psalm 90:10 in the Bible, so the Tree of Life representation of Adam Kadmon (אדם קדמזן), or "Heavenly Man," embodies the same parameter 70. Is this more than coincidence?The 2-dimensional Sri Yantra contains 70 points. They are made up of the bindu (a Sanskrit term, meaning "dot" or "point") at the centre of the central triangle and the 69 corners of the 43 triangles that surround it. The bindu is the source of all manifestation — both physical and superphysical
The outer Tree of Life consists of its root, trunk & branches. Its root comprise the two yods (one white, coinciding with Tiphareth, the other black, coinciding with Daath) whose projections onto the plane of the (7+7) enfolded polygons of the inner Tree of Life coincide with the endpoints of the root edge. The trunk consists of the 34 other yods (coloured red) that make up the mathematical sequence of the point (Kether), line (Chokmah-Binah), triangle (Chesed-Geburah-Tiphareth) & tetrahedron (Netzach-Hod-Yesod-Malkuth). The branches comprise the 34 blue yods in the 11 tetractyses outside the root and trunk of the Tree of Life. The black yod corresponds to the bindu in the 2-dimensional Sri Yantra, the white yod corresponds to the lowest (white) corner of its central triangle, the 34 blue yods correspond to the 34 blue corners of the21 triangles in the lower half of the Sri Yantra and the 34 red yods correspond to the 34 red corners of the 21 triangles in its upper half. The upper and lower halves of the Sri Yantra, respectively, correspond to the root & trunk of the outer Tree of Life and to its branches.
The 14 enfolded polygons of the inner Tree of Life have 70 corners. 34 red corners outside the root edge are associated with one set of seven polygons and 34 blue corners are associated with the other set. The 2-dimensional Sri Yantra comprises 70 points. The 21 triangles in one half of the Sri Yantra that surround its central triangle have 34 red corners; the 21 triangles in its other half have 34 blue corners. The central triangle has one corner (the lowest one, coloured white) that is unshared with any of the 42 triangles surrounding it. This corner corresponds to the white, lower endpoint of the root edge. The black bindu at the centre of the Sri Yantra corresponds to the black, upper endpoint of the root edge. The reason for these two correspondences is as follows: the bindu is the seed source of Divine Creation, whilst the upper endpoint coincides with Daath, out of which the seven Sephiroth of Construction expressing the objective nature of God emanate. They have analogous, metaphysical meanings. Moreover, the white corner is the lowest corner of the fifth, downward-pointing (Shakti) triangle that has no upward-pointing (Shiva) counterpart. As in the case of the lower endpoint of the root edge — a point which does not shape any part of the 14 enfolded polygons that extend beyond this root edge — this corner is the only corner that does not participate in the shaping of the 42 surrounding triangles. It is the only corner belonging to the primary set of nine parent Shiva & Shakti triangles that is not a corner of the 42 triangles that they generate. The bindu and this corner are the counterparts of the endpoints of the root edge, whilst the 34 corners of each set of seven enfolded polygons are the counterparts of the 34 corners of the 21 triangles in each half of the 2-dimensional Sri Yantra.
