The System of the Vedanta according to Badarayana's Brahma-Sutras and Cankara's Commentary c8.s6.t7.5

c8.s6.t7.5

According to this the interaction of body and soul must be conceived as follows: the *Indriyas* are simply the powers or functions of the *Karanas*, *i.e.*, of the material organs; these they produce out of themselves and remain in the closest and most intimate connection with them; these *Indriyas* have their common centre in the *Manas*; the *Manas* is homogeneous with them and itself an *Indriyam*; it dwells, large as the point of an awl, in the heart; in the *Manas*, filling it completely and (except by liberation and temporarily in deep sleep) inseparably connected with it, is the Soul, which, by the mediation of the *Manas* and *Indriyas*, governs the movements of the *Karanas* and receives their impressions; while the *Mukhya Prâna* with its five branches pervades the whole body and provides for its nutrition on behalf of the soul; it is subject to the soul, but, leaving death out of the question, a connection between the two is not discoverable.
