The answer to the first question, suggested by the second, which is the reply of the teacher to the pupil, contains in a single phrase one of the most essential truths of Occult Philosophy. It indicates the existence of things imperceptible to our physical senses which are of far greater importance, more real and more permanent, than those that appeal to these senses themselves. Before the Lanoo can hope to understand the transcendentally metaphysical problem contained in the first question, he must be able to answer the second; while the very answer he gives to the second will furnish him with the clue to the correct reply to the first. In the Sanskrit Commentary on this Stanza, the terms used for the concealed and the unrevealed Principle are many. In the earliest MSS. of Indian literature this Unrevealed Abstract Deity has no name. It is generally called “That” (Tad, in Sanskrit), and means all that is, was, and will be, or that can be so received by the human mind. Among such appellations given—of course, only in Esoteric Philosophy—as the “Unfathomable Darkness,” the “Whirlwind,” etc., it is also called the “It of the Kâlahansa,” the “Kâla‐ham‐sa,” and even the “Kâli Hamsa” (Black Swan). Here the m and the n are convertible, and both sound like the nasal French an or am. As in the Hebrew so also in the Sanskrit many a mysterious sacred name conveys to the profane ear no more than some ordinary, and often vulgar word, because it is concealed anagrammatically or otherwise. This word Hansa, or Hamsa, is just such a case. Hamsa is equal to “A‐ham‐sa”—three words meaning “I am He”; while divided in still another way it will read “So‐ham,” “He [is] I.” In this single word is contained, for him who understands the language of wisdom, the universal mystery, the doctrine of the identity of man’s essence with god‐essence. Hence the glyph of, and the allegory about, Kâlahansa (or Hamsa), and the name given to Brahman (neuter), later on to the male Brahmâ, of Hamsa‐ vâhana, “he who uses the Hamsa as his vehicle.” The same word may be read “Kâlaham‐sa,” or “I am I, in the eternity of time,” answering to the Biblical, or rather Zoroastrian, “I am that I am.” The same doctrine is found in the _Kabalah_, as witness the following extract from an unpublished MS. by Mr. S. Liddell McGregor Mathers, the learned Kabalist:
