Mbh 12.194.2b

The Soul exists as a witness (without acting). All that is above the two feet, all that is behind, and all that is above, are seen by the Soul. Know that the Soul pervades the entire being without any space being left unoccupied. All men should know the senses, the mind, and the understanding fully. The three states or qualities called Darkness, Passion, and Goodness, exist, dependent on the senses, the mind, and the understanding.[604] Man, by apprehending with the aid of his intelligence, the manner in which creatures come and leave the world, is sure to gradually attain to steadfast tranquillity. The three qualities (already mentioned, viz., Darkness, Passion, and Goodness), lead the understanding (to worldly attachments). In this respect, the Understanding (or Intelligence) is identical with the Senses and the Mind. The Understanding, therefore, is identical with the six (the five senses and the mind), and also with the objects comprehended by it. When, however, the Understanding is destroyed, the three qualities (of Darkness, Passion, and Goodness) are incapable of leading to action.[605] This universe of immobile and mobile things consists of that intelligence. It is from that Intelligence that everything arises and it is into it that everything subsides. For this reason, the scriptures indicate that everything is a manifestation of Intelligence. That by which one hears is the ear. That by which one smells is called the organ of smell, and that by which one distinguishes the tastes is called the tongue. By the coat that covers the body one acquires perception of touch. That which is called the Intelligence undergoes modifications.[606] When the Intelligence desires anything it comes to be called Mind. The foundations upon which the Intelligence rests are five in number, each serving a different purpose. They are called the senses. The invisible principle, viz., Intelligence rests on them.
