Mbh 12.217.1b

[780] Purusha is the apprehender of all the transformations of Prakriti (but cannot be apprehended himself). He transcends (in respect of his original nature) all attributes. As regards Purusha and the Supreme Soul again, both of them are incomprehensible. In consequence again of both of them being without attributes by which they can be distinguished, both are highly distinguished from all else.[781] A turbaned person has his head circled with three folds of a piece of cloth. (The person, however, is not identical with the turban he wears). After the same manner the embodied Soul is invested with the three attributes of Goodness, Passion, and Darkness. But though thus invested, the Soul is not identical with those attributes. Hence these four topics, which are covered by these fourfold considerations, should be understood.[782] One who understands all this is never stupefied when one has to draw conclusions (in respect of all subjects of enquiry). He that is desirous of attaining to high prosperity should become pure in mind, and betaking himself to austere practices in respect of the body and the senses, should devote himself to yoga without desire of fruits. The universe is pervaded by yoga power secretly circulating through every part of it and illumining it brightly. The sun and the moon shine with effulgence in the firmament of the heart in consequence of yoga power. The result of yoga is Knowledge. Yoga is talked of very highly in the world.[783] Whatever acts are destructive of Passion and Darkness constitute yoga in respect of its real character. Brahmacharya and abstention from injury are said to constitute yoga of the body; while restraining mind and speech properly are said to constitute yoga of the mind. The food that is obtained in alms from regenerate persons conversant with the ritual is distinguished from all other food. By taking that food abstemiously, one's sins born of Passion begin to fade.
