sa cokto vai pṛthak strītvaṃ puruṣatvaṃ tathākarot /

When they thus showed disregard at the creation of the worlds, the high-souled Brahmā grew very wrathful; then was produced there a male[4] like to the sun, possessed of an immense body, the body being half man’s and half woman’s. “Divide thyself” said the god, and then disappeared. And he being thus accosted separated the female and male natures; and he divided the male nature into eleven parts. Then the divine lord divided the male and female natures into many parts with men, gentle and cruel, calm, black and white.
