It is in strict analogy with the attributes of this Brahma in both the spiritual and material worlds, that the evolution of the Dhyân‐Chohanic Essences takes place; the characteristics of the latter being reflected, in their turn, in Man, collectively, and in each of his principles; _every one of which contains in itself, in the same progressive order, a portion of their various __“__Fires__”__ and Elements_. Stanza V. The Evolution of the Second Race. 18. The Sons of Yoga. 19. The Sexless Second Race. 20. The Sons of the “Sons of Twilight.” 21. The “Shadow,” or the Astral Man, retires within, and man develops a Physical Body. 18. THE FIRST(249) WERE THE SONS OF YOGA. THEIR SONS, THE CHILDREN OF THE YELLOW FATHER AND THE WHITE MOTHER. In the later Commentary, the sentence is translated: _The Sons of the Sun and of the Moon, the nursling of Ether [or the __“__Wind__”__] (a)_.... _They were the shadows of the Shadows of the Lords (b). They [the shadows] expanded. The Spirits of the Earth clothed them; the Solar Lhas warmed them [__i.e.__, preserved the Vital Fire in the nascent physical Forms]. The Breaths had life, but had no understanding. They had no Fire or Water of their own (c)._ (_a_) Remember in this connection the _Tabula Smaragdina_ of Hermes, the Esoteric meaning of which has seven keys to it. The Astro‐chemical is well known to students, the Anthropological may now be given. The “One Thing” mentioned in it is Man. It is said: The Father of that One Only Thing is the Sun; its Mother the Moon; the Wind carries it in his bosom, and its Nurse is the Spirituous Earth. In the Occult rendering of the same it is added: “and _Spiritual_ Fire is its instructor [Guru].” This Fire is the Higher Self, the Spiritual Ego, or that which is eternally reïncarnating under the influence of its lower personal Selves, changing with every re‐birth, full of Tanha or desire to live. It is a strange law of Nature that, on this plane, the higher (Spiritual) Nature should be, so to say, in bondage to the lower. Unless the Ego takes refuge in the Âtman, the ALL‐SPIRIT, and merges entirely into the essence thereof, the personal Ego may goad it to the bitter end. This cannot be thoroughly understood unless the student makes himself familiar with the mystery of evolution, which proceeds on triple lines—Spiritual, Psychic and Physical.
