1.85.16

ghrāṇena gandhaṃ jihvayātho rasaṃ ca tvacā sparśaṃ manasā veda bhāvam |
ityaṣṭakehopacitiṃ ca viddhi mahātmanaḥ prāṇabhṛtaḥ śarīre || 16 ||

"Ashtaka said, 'O tell me, I ask thee because I have my doubts. Doth a being that hath received a human form enter the womb in its own shape or in some other? How doth it also acquire its distinct and visible shape, eyes and ears and consciousness as well? Questioned by me, O, explain it all! Thou art, O father, one acquainted with the acts and sayings of great beings.' Yayati answered, 'According to the merits of one's acts, the being that in a subtile form co-inheres in the seed that is dropped into the womb is attracted by the atmospheric force for purposes of re-birth. It then developeth there in course of time; first it becomes the embryo, and is next provided with the visible physical organism. Coming out of the womb in due course of time, it becometh conscious of its existence as man, and with his ears becometh sensible of sound; with his eyes, of colour and form; with his nose, of scent; with his tongue, of taste; by his whole body, of touch; and by his mind, of ideas. It is thus, O Ashtaka, that the gross and visible body developeth from the subtile essence.'
