Mbh 12.299.3d

Like one afflicted with congenital blindness and, therefore, incapable of seeing his way, the sensualist, with soul confined in an opaque case, seems to be surrounded by a mist and fails to see (the true object for which he should strive). As merchants, going across the sea, make profits proportioned to their capital, even so creatures, in this world of mortals, attain to ends according to their respective acts. Like a snake devouring air, Death wanders in this world made up of days and nights in the form of Decrepitude and devours all creatures. A creature, when born, enjoys or endures the fruits of acts done by him in his previous lives. There is nothing agreeable or disagreeable which one enjoys or endures without its being the result of the acts one has done in one's previous lives. Whether lying or proceeding, whether sitting idly engaged in his occupations, in whatever state a man may be, his acts (of past lives) good or bad always approach him. One that has attained to the other shore of the ocean, wishes not to cross the main for returning to the shore whence he had sailed.[1567] As the fisherman, when he wishes, raises with the help of his chord his boat sunk in the waters (of a river or lake), after the same manner the mind, by the aid of Yoga-contemplation, raises Jiva sunk in the world's ocean and unemancipated from consciousness of body.[1568] As all rivers running towards the ocean, unite themselves with it, even so the mind, when engaged in Yoga, becomes united with primal Prakriti.[1569] Men whose minds become bound by diverse chains of affection, and who are engulfed in ignorance, meet with destruction like houses of sand in water.[1570] That embodied creature who regards his body as only a house and purity (both external and internal) as its sacred water, and who walks along the path of the understanding, succeeds in attaining to happiness both here and hereafter.
