The Secret Doctrine vol. 1, Stanza II.6
The “Divine Thought” does not imply the idea of a Divine thinker. The Universe, not only past, present, and future—which is a human and finite idea expressed by finite thought—but in its totality, the Sat (an untranslateable term), the absolute being, with the Past and Future crystallized in an eternal Present, is that Thought itself reflected in a secondary or manifest cause. Brahma (neuter) as the Mysterium Magnum of Paracelsus is an absolute mystery to the human mind. Brahma, the male-female, its aspect and anthropomorphic reflection, is conceivable to the perceptions of blind faith, though rejected by human intellect when it attains its majority. (See Part II., “Primordial Substance and Divine Thought.”)
Hence the statement that during the prologue, so to say, of the drama of Creation, or the beginning of cosmic evolution, the Universe or the “Son” lies still concealed “in the Divine Thought,” which had not yet penetrated “into the Divine Bosom.” This idea, note well, is at the root, and forms the origin of all the allegories about the “Sons of God” born of immaculate virgins.
