(_a_) “When the One becomes Two, the Three‐fold appears”: to wit, when the One Eternal drops its reflection into the region of Manifestation, that reflection, the Ray, differentiates the Water of Space; or, in the words of the _Book of the Dead_: “Chaos ceases, through the effulgence of the Ray of Primordial Light dissipating total darkness, by the help of the great magic power of the Word of the [Central] Sun.” Chaos becomes male‐ female, and Water, incubated by Light, and the Three‐fold Being issues as its “First‐born.” “Ra [or Osiris‐Ptah] creates his own Limbs [like Brahmâ], by creating the Gods destined to personify his phases,” during the Cycle.(367) The Egyptian Ra, issuing from the Deep, is the Divine Universal Soul in its manifested aspect, and so is Nârâyana, the Purusha, “concealed in Âkâsha, and present in Ether.” This is the metaphysical explanation, and refers to the very beginning of Evolution, or, as we would rather say, of Theogony. The meaning of the Stanza, when explained from another standpoint in its reference to the mystery of man and his origin, is still more difficult to comprehend. In order to form a clear conception of what is meant by the One becoming Two, and then being transformed into the Three‐fold, the student has to make himself thoroughly acquainted with what we call Rounds. If he refers to _Esoteric Buddhism_—the first attempt to sketch out an approximate outline of archaic cosmogony—he will find that by a Round is meant the serial evolution of nascent material Nature, of the seven Globes of our Chain,(368) with their mineral, vegetable and animal kingdoms; man being included in the latter and standing at the head of it, during the whole period of a Life‐Cycle, which latter would be called by the Brâhmans a “Day of Brahmâ.” It is, in short, one revolution of the “Wheel” (our Planetary Chain), which is composed of seven Globes, or seven separate “Wheels,” in another sense this time. When evolution has run downward into matter from Globe A to Globe G, it is one Round. In the middle of the fourth revolution, which is our present Round, “Evolution has reached its acme of physical development, crowned its work with the perfect physical man, and, from this point, begins its work spirit‐ward.” All this needs little repetition, as it is well explained in _Esoteric Buddhism_. That which was hardly touched upon, however, and of which the little that was said has misled many, is the origin of man, and it is upon this that a little more light may now be thrown, just enough to make the Stanza more comprehensible, as the process will be fully explained only in its legitimate place, in Volume II.
