Taste, all liquid secretions, and the tongue represent the three attributes of Water. Scents, the nose, and the body are the triple properties of Earth. The great (primal) elements are five. The mind is the sixth. The senses and the mind, O Bharata, are (the sources of all) the perceptions of a living creature. The seventh is called the understanding; and the eighth is the soul. The senses are for perceiving; the mind (unable to deal with those perceptions) produces uncertainty. The understanding reduces all perceptions to certainty. 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. 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.
