It has been said that before we can properly understand the character of any deity we would have to know the meaning and the numbers attached to each letter in the name, for in this way the powers and functons of the various gods were indicated. If we take as examples names familiar to everyone, Brahma, Vishnu, and Rudra, the three aspects of Parabrahm in manifestation, and analyse them in the same way as the roots, they will be found to yield up their essential meaning. Form the union of B, life, R, breath, and Ma, the producer, I would translate Brahma as “the creative breath of life.” Vishnu similarly analysed is the power that “pervades, expands, and preserves;” I infer this from the union of V, whose force is pervasion, Sh, expansion, and N, continuation. Rudra is “the breath that absorbs the breath.” Aum is the most sacred name of all names; it is held to symbolize the action of the Great breath from its dawn to its close: it is the beginning, A, the middle, U, and the close M. It is also an affirmation of the relation of our spiritual nature to the universal Deity whose aspects are Brahma, Vishnu, and Rudra. I shall have more to say of the occult power of this word later on. Taken in conjunction with two other words, it is “the threefold designation of the Supreme Being.” Om Tat Sat has a significance referable to a still higher aspect of Deity than that other Trinity; the Om here signifies that it is the All; Tat that it is self-existent or self-evolved; I think the repetition of the T in Tat gives it this meaning: Sat would signify that in it are contained the seeds of all manifestation.
