Mbh 12.204.1b

[685] Above the senses is the mind; above the mind is the understanding; above the understanding is the Soul; above the Soul is the Supreme or Great. From the Unmanifest hath sprung the Soul; from the Soul hath sprung the Understanding; from the Understanding hath sprung the Mind. When the Mind becomes associated with the senses, then it apprehends sound and the other objects of the senses. He who casts off those objects, as also all that are manifest, he who liberates himself from all things that arise from primordial matter, being so freed, enjoys immortality.[686] The Sun rising diffuses his rays. When he sets, he withdraws unto himself those very rays that were diffused by him. After the same manner, the Soul, entering the body, obtains the fivefold objects of the senses by diffusing over them his rays represented by the senses. When, however, he turns back, he is said to set by withdrawing those rays unto himself.[687] Repeatedly led along the path that is created by acts, he obtains the fruits of his acts in consequence of his having followed the practice of acts.[688] Desire for the objects of the senses keeps away from a person who does not indulge in such desire. The very principle of desire, however, leaves him who has beheld his soul, which, of course, is entirely free from desire.[689] When the Understanding, freed from attachment to the objects of the senses, becomes fixed in the mind, then does one succeed in attaining to Brahma, for it is there that the mind with the understanding withdrawn into it can possibly be extinguished. Brahma is not an object of touch, or of hearing, or of taste, or of sight, or of smell, or of any deductive inference from the Known. Only the Understanding (when withdrawn from everything else) can attain to it.
