Clearly, if the soul produced four faculties, all different from each other, no less and no more, this must have come about through the power contained within it, which was able to bring this forth, no less and no more. If so, the action that the soul performs through one fissure is different from the action it performs through a different fissure. Accordingly, hearing is rooted in one fissure, vision in another, smell in another and speech in yet another.
The truth is that according to the powers contained in the inner soul, so it was that through one power the soul was drawn to one of the organs suited and ready for that power to function, and the soul broke through it and went out. Through a different inherent power, the soul was drawn to a different organ, and broke through it and went out. Thus the Otzrot Chaim states: “But the wise will understand that the light of the brain is called AV, while the light of the ear is called SaG...” (Gate of TaNTA, end of ch. 2, gloss).
