Mbh 12.317.1b

The concentration of the mind in such a way as to destroy all difference between the contemplator, the object contemplated, and the act of contemplation along with subjugation of the senses, is of another kind. The first kind of Yoga is said to be that possessed of attributes; the second kind is said to be that freed from attributes.[1657] Then, again, regulation of the breath is Yoga with attributes. In Yoga without attributes, the mind, freed from its functions, should be fixed. Only the regulation of the breath which is said to be endued with attributes should, in the first instance, be practised, for, O ruler of Mithila, if the breath (that is inhaled and suspended) be exhaled without mentally reflecting the while upon a definite image (furnished by a limited mantra), the wind in the neophyte's system will increase to his great injury.[1658] In the first Yama of the night, twelve ways of holding the breath are recommended. After sleep, in the last Yama of the night, other twelve ways of doing the same have been laid down. Without doubt, one endued with tranquillity, of subdued senses, living in retirement, rejoicing in one's own self, and fully conversant with the import of the scriptures, should (regulating one's breath in these four and twenty ways) fix one's Soul (on the Supreme Soul).[1659] Dispelling the five faults of the five senses, viz., (withdrawing them from their objects of) sound, form, touch, taste, and scent, and dispelling those conditions called Pratibha and Apavarga, O ruler of the Mithilas, all the senses should be fixed upon the mind. The mind should then be fixed on Consciousness, O king, Consciousness should next be fixed on intelligence or Buddhi, and Buddhi, should then be fixed on Prakriti.
