Mbh 14.25.1b

Whatever is thought of by the mind, whatever is uttered by speech, whatever is heard by the ear, whatever is seen by the eye, whatever is touched by the (sense of) touch, whatever is smelt by the nose, constitute oblations of clarified butter which should all, after restraining the senses with the mind numbering the sixth, be poured into that fire of high merits which burns within the body, viz., the Soul.[70] The sacrifice constituted by Yoga is going on as regards myself. The spring whence that sacrifice proceeds is that which yields the fire of knowledge. The upward life-wind Prana is the Stotra of that sacrifice. The downward life-wind Apana is its Sastra. The renunciation of everything is the excellent Dakshina of that sacrifice. Consciousness, Mind, and Understanding--these becoming Brahma, are its Hotri, Adhwaryyu, and Udgatri. The Prasastri, his Sastra, is truth.[71] Cessation of separate existence (or Emancipation) is the Dakshina. In this connection, people conversant with Narayana recite some Richs. Unto the divine Narayana were animals offered in days of yore.[72] Then are sung some Samanas. On that topic occurs an authority. O timid one, know that the divine Narayana is the soul of all.'"'"
