Mbh 14.25.1a

"'"The Brahmana said, 'In this connection is recited the ancient story of what the institution is of the Chaturhotra (sacrifice). The ordinances are now being duly declared of that in its entirety. Listen to me, O amiable lady, as I declare this wonderful mystery. The agent, the instrument, the action and Emancipation,--these, O beautiful lady, are the four sacrificing priests by whom the universe is enveloped. Hear in its entirety the assignment of causes (relating to this topic). The nose, the tongue, the eye, the skin, the ear numbering the fifth, the mind, and the understanding,--these seven should be understood as being caused by (the knowledge of) qualities. Smell, taste, colour, sound, touch, numbering the fifth, the objects of the mind, and the objects of the understanding, these seven are caused by action. He who smells, he who eats, he who sees, he who speaks, he who hears, numbering the fifth, he who thinks, and he who understands--these seven should be known as caused by the agent. Possessed of qualities, these enjoy their own qualities, agreeable or disagreeable.[68] As regards the Soul, that is destitute of qualities. These seven are the causes of Emancipation. With them that are learned and possessed of sufficient understanding, the qualities, which are in the position of deities, eat the oblations, each in its proper place, and agreeably to what has been ordained. The person who is destitute of learning, eating diverse kind of food, becomes seized with the sense of mineness.[69] Digesting food for himself, he becomes ruined through the sense of mineness. The eating of food that should not be eaten, and the drinking of wine, ruin him. He destroys the food (he takes), and having destroyed that food, he becomes destroyed himself. The man of learning, however, being possessed of puissance, destroys his food for reproducing it. The minutest transgression does not arise in him from the food he takes.
