Mbh 14.19.2a

"'"The Brahmana continued, 'Thus addressed by me, that intelligent disciple, O slayer of Madhu, once more asked me about this religion of Emancipation that is so difficult to explain. How does this food that is eaten from time to time become digested in the stomach? How does it become transformed into juice? How, again, into blood? How does it nourish the flesh, the marrow, the sinews, the bones? How do all these limbs of embodied creatures grow? How does the strength grow of the growing man? How occurs the escape of all such elements as are not nutritive, and of all impurities separately? How does this one inhale and again, exhale? Staying upon what particular part does the Soul dwell in the body? How does Jiva, exerting himself, bear the body? Of what colour and of what kind is the body in which he dwells again (leaving a particular body)? O holy one, it behoveth thee to tell me all this accurately, O sinless one,'--even thus was I interrogated by that learned Brahmana, O Madhava. I replied unto him, O thou of mighty arms, after the manner I myself had heard, O chastiser of all foes. 'As one placing some precious object in one's store-room should keep one's mind on it, so, placing the mind within one's own body, one should then, restraining all the senses, seek after the Soul, avoiding all heedlessness. One would, becoming always assiduous in this way and gratified with one's own self, within a very short time attain to that Brahma by beholding which one would become conversant with Pradhana.[39] He is not capable of being seized by the eye; nor even by all the senses.[40] It is only with the lamp of the mind that great Soul can be seen. He has hands and feet on all sides; he has ears on all sides; he dwells, pervading all things in the world.[41] Jiva beholds the Soul as extracted from the body (like the stalk from a blade of Saccharum Munja, when knowledge comes).
