Mbh 12.248.1a

"'"Vyasa said, 'The mind creates (within itself) numerous ideas (of objects or existent things). The Understanding settles which is which. The heart discriminates which is agreeable and which is disagreeable. These are the three forces that impel to acts. The objects of the senses are superior to the senses. The mind is superior to those objects. The understanding is superior to mind. The Soul is regarded as superior to Understanding. (As regards the ordinary purposes of man) the Understanding is his Soul. When the understanding, of its own motion, forms ideas (of objects) within itself, it then comes to be called Mind.[1049] In consequence of the senses being different from one another (both in respect of their objects and the manner of their operation), the Understanding (which is one and the same) present different aspect in consequence of its different modifications. When it hears, it becomes the organ of hearing, and when it touches, it becomes the organ of touch. Similarly, when it sees, it becomes the organ of vision, and when it tastes, it becomes the organ of taste, and when it smells, it becomes the organ of scent. It is the Understanding that appears under different guises (for different functions) by modification. It is the modifications of the Understanding that are called the senses. Over them is placed as their presiding chief (or overseer) the invisible Soul. Residing in the body, the Understanding exists in the three states (of Sattwa, Rajas, and Tamas). Sometimes it obtains cheerfulness, sometimes it gives way to grief; and sometimes its condition becomes such that it is united with neither cheerfulness nor grief. The Understanding, however, whose chief function (as already said) is to create entities, transcends those three states even as the ocean, that lord of rivers, prevails against the mighty currents of the rivers that fall into it.[1050] When the Understanding desires for anything, it comes to be called by the name of Mind.
