Mbh 12.217.1c

A yogin subsisting upon such food finds his senses gradually withdrawn from their objects. Hence, he should take only that measure of food which is strictly necessary for the support of his body. (Another advice that may be offered is that) that knowledge which one obtains gradually by mind devoted to yoga should cheerfully be made one's own during one's last moments by a forcible stretch of power.[784] The embodied Soul, when divested of Rajas (does not immediately attain to Emancipation but) assumes a subtile form with all the senses of perception and moves about in space. When his mind becomes unaffected by acts, he, in consequence of such renunciation (loses that subtile form and) becomes merged in Prakriti (without however, yet attaining to Brahma or Emancipation which transcends Prakriti).[785] After the destruction of this gross body, one who through absence of heedlessness escapes from all the three bodies (viz., the gross, the subtile and the karana) succeeds in attaining to Emancipation.[786] The birth and death of creatures always depend upon the cause constituted by original Ignorance (or Avidya). When knowledge of Brahma arises, necessity no longer pursues the person. Those, however, that accept what is the reverse of truth (by believing that to be Self which is really not-Self) are men whose understandings are always taken up with the birth and death of all existent things. (Such people never dream even of Emancipation).[787] Supporting their bodies by aid of patience, withdrawing their hearts from all external objects by the aid of their understanding, and withdrawing themselves from the world of senses, some yogins adore the senses in consequence of their subtility.
