A—This represents God, creative force, the Self, the I, the beginning or first cause. “Among letters I am the vowel A,” says Krishna in the Bagavad. It is without colour, number or form.
R—This is motion, air, breath or spirit; it is also abstract desire, and here we find the teaching of the Rig-Veda in harmony. “Desire first arose in It which was the primal germ of mind, and which sages, searching with their intellect, have discovered in their hearts to be the bond which connects Entity with non-Entity.” The corresponding colour of this letter is Red.
H (hay) and L—Motion awakens Heat and Light which correspond respectively to H and L. That primordial ocean of being, says the book of Dzyan, was “fire and heat and motion:” which are explained as the noumenal essences of these material manifestations. The colour of H is Orange, of L yellow. L also conveys the sense of radiation.
Y (yea)—This letter signifies condensation, drawing together, the force of attraction, affinity. Matter at the stage of evolution to which this refers is gaseous, nebulous, or ethereal: the fire-mists in space gather together to become worlds. The colour Y is green.
W (way)—Water is the next element in manifestation: in cosmic evolution it is spoken of as chaos, the great Deep; its colour, I think, is indigo. After this stage the elements no longer manifest singly, but in pairs, or with a dual aspect.
G (gay) and K—Reflection and Hardness; matter becomes crystalline or metalic: the corresponding colour is blue.
S and Z—A further differentiation; matter is atomic: the abstract significance of number or seed is attached to these letters: their colour is violet.
J and Tchay—Earth and gross Substance: this is the lowest point in evolution; the worlds have now condensed into solid matter. The colour of these letters is orange.
N and Ng—Some new forces begin to work here; the corresponding sounds have, I think, the meaning of continuation and transformation or change: these new forces propel evolution in the upward or ascending arc: their colour is yellow.
D and T—The colour of these letters is red. The involution of the higher forces into the lower forms alluded to before now begins. D represents this infusion of life into matter; it is descent and involution, death or forgetfulness, perhaps, for a time to the incarnating power. T is evolution, the upward movement generating life; the imprisoned energies surge outwards and vegetation begins.
Ith and Ish—These correspond respectively to growth or expansion and vegetation; the earth, as Genesis puts it, “puts forth grass and herbs and trees yielding fruit.” The colour of these letters is green.
B and P—After the flora the fauna. B is Life or Being, animal and human. Humanity appears; B is masculine, P feminine. P has also a meaning of division, differentiation or production, which may refer to maternity. The colour here is blue.
