The first Being is, obviously, unthinkable, limitless, eternal; it is at once the One and the All, “creator” and “lord” of the world. Some even identified it with the universe; others sought it in the “person” (puruṣa) present in the sun, the moon, the word, etc., still others in the “limitless” that sustains the world, life, and consciousness. Among the names of the first Being, the one that took precedence from the beginning was Brahman.
