Mbh 12.219.3b

Upon the senses rest all acts (that lead to heaven), as also renunciation (leading to the attainment of Brahma), and also the ascertainment of truth in respect of all topics of enquiry. The learned say that ascertainment (of truth) is the highest object of existence, and that it is the seed or root of Emancipation; and with respect to Intelligence, they say that leads to Emancipation and Brahma.[815] That person who regards this union of perishable attributes (called the body and the objects of the senses) as the Soul, feels, in consequence of such imperfection of knowledge, much misery that proves again to be unending. Those persons, on the other hand, who regard all worldly objects as not-Soul, and who on that account cease to have any affection or attachment for them, have never to suffer any sorrow for sorrow, in their case stands in need of some foundation upon which to rest. In this connection there exists the unrivalled branch of knowledge which treats of Renunciation. It is called Samyagradha. I shall discourse to thee upon it. Listen to it for the sake of thy Emancipation. Renunciation of acts is (laid down) for all persons who strive earnestly for Emancipation. They, however, who have not been taught correctly (and who on that account think that tranquillity may be attained without renunciation) have to bear a heavy burthen of sorrow. Vedic sacrifices and other rites exist for renunciation of wealth and other possessions. For renunciation of all enjoyments exist vows and fasts of diverse kinds. For renunciation of pleasure and happiness, exist penances and yoga. Renunciation, however, of everything, is the highest kind of renunciation. This that I shall presently tell thee is the one path pointed out by the learned for that renunciation of everything. They that betake themselves to that path succeed in driving off all sorrow. They, however, that deviate from it reap distress and misery.
