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. F and V--The colour is violet. Evolution moves still upwards, entering the ethereal planes once more. Lightness and vastness are the characteristics of this stage: we begin to permeate with part of our nature the higher spheres of being and reach the consummation in the last stage, represented by M--which has many meanings; it is thought, it is the end or death to the personality, it is the Receiver into which all flows, it is also the Symbol of maternity in a universal sense, it has this meaning when the life impulse (which is always represented by a vowel) follows it, as in "ma." It is the Pralaya of the worlds; the lips close as it is uttered. Its colour is indigo. O--The last vowel sound symbolizes abstract space, the spirit assumes once more the garment of primordial matter; it is the Nirvana of eastern philosophy. I will now try to show how the abstract significance of these sound reveals a deeper meaning in the roots of Aryan language than philologists generally allow. Prof. Max Muller says in the introduction to Biographies of Words. "Of ultimates in the sense of primary elements of language, we can never hope to know anything," and he also asserts that the roots are incapable of further analysis. I will endeavour now to show that this further analysis can be made.
