The phrase in Rule XV which says "that blend the fire and water" has reference to the effect produced at the [612] point of condensation, after the great words bringing about that effect have been pronounced. This rule is almost incapable of explanation and it is not permitted to me to give to you the words that effect this process. Only some hints may be given which will serve to encourage the true aspirant to think and may alas, only irritate the casual thinker who seeks easy and quick methods and formulas through which to work. Heat and moisture are present in the production of all forms of life, but the great mystery (and almost the final mystery to be explained to the adept) is how the merging of three fires can produce moisture or the watery element. This problem and this phenomenon constitute the basis of the Great Illusion to which the ancient books refer; through the agency of the combination, the enveloping maya is produced. There is, in reality, no such thing as water; the watery sphere, the astral plane, is, could you but realize it, an illusory effect and has no real existence. Yet - in time and space and to the understanding of the witnessing consciousness - it is more real than that which it hides and conceals. I cannot make this clearer in words. It is only possible to suggest to the intelligent student that the light of his soul (reflected in his mind) and the energy of form (as expressed in his etheric body) are for him, in the realm of temporary duality, his two basic realities. The watery nature of his astral experience in which these two aspects of divinity seem (again illusion, be it noted) to meet and work is but a glamorous phenomenon and in an occult sense is not based on fact. Any true aspirant knows that his spiritual progress can be gauged in terms of his freedom from this illusion and of his release into the clear air and pure light of his spiritual consciousness. In its consciousness, the animal kingdom works with the second of these two basic realities, and for it the life of the etheric body and the force which governs the animal or material nature are the [613] prime expression of truth. Yet the animal is beginning to sense dimly the world of illusion and possesses certain psychic powers and senses which recognize yet fail to interpret the astral plane. The veil of illusion is beginning to fall before the eyes of the animal but it knows it not. The human being has wandered for ages in the world of illusion, for it is of his own creating. Yet man in his turn, from the standpoint of consciousness, has contact with both the realities and learns little by little to dissipate the illusion by the steady growth of the radiant light of the soul. May I pause here to remind you that duality is only a stage on the evolutionary arc, leading eventually to the realization of unity.
