3. He is Brahma; he is Indra; he is Prajāpati; [he is] all these gods; and these five gross elements (mahā-bhūtāni), namely earth (pṛthivī), wind (vāyu), space (ākāśa), water (āpas), light (jyotīṁṣi); these things and those which are mingled of the fine (kṣudra), as it were; origins (bīja) of one sort and another: those born from an egg (aṇḍa-ja), and those born from a womb (jāru-ja), and those born from sweat (sveda-ja), and those born from a sprout (udbhij-ja); horses, cows, persons, elephants; whatever breathing thing there is here—whether moving or flying, and what is stationary.

All this is guided by intelligence, is based on intelligence. The world is guided by intelligence. The basis is intelligence. Brahma is intelligence.
