Mbh 6.26.8b

For the heart that follows in the wake of the sense moving (among their objects) destroys his understanding like the wind destroying a boat in the waters.[149] Therefore, O thou of mighty arms, his is steadiness of mind whose senses are restrained on all sides from the objects of sense. The restrained man is awake when it is night for all creatures; and when other creatures are awake that is night to a discerning Muni.[150] He into whom all objects of desire enter, even as the waters enter the ocean which (though) constantly replenished still maintains its water-mark unchanged--(he) obtains peace (of mind) and not one that longeth for objects of desire. That man who moveth about, giving up all objects of desire, who is free from craving (for enjoyments) and who hath no affection and no pride, attaineth to peace (of mind). This, O Partha, is the divine state. Attaining to it, one is never deluded. Abiding in it one obtains, on death, absorption into the Supreme Self.’”
