He is the looker-on, who, being close at hand, is the seer, Himself unengaged. As, among the officiating priests and the sacrificer engaged in the work of the sacrifice, another, standing apart, unengaged, skilled in the lore of the sacrifice, is the observer of the merits and faults of the doings of priests and sacrificer: just so, with regard to the doings of effect and instrument, another, unengaged, distinct from them, by reason of His nearness to all those doings, is their close seer, the looker-on. Or else: the body, the eye, the mind, the intellect and the Self are seers; of these the body is the outer seer, and inward from it, more and more inward, the inmost, the close, is the Self, the seer; and since there is no seer beyond Him, more inward, He, by being a seer of a surpassing nearness, is the looker-on; or, as the looker-on of a sacrifice, He is the looker-on because He makes all His object. And He is the consenter: consent is approval, a satisfaction in the doings of those who are doing the act, and the maker of that satisfaction is the consenter. Or else, the consenter is He who, though Himself unengaged in the doings of effect and instrument, is conceived to be favourable to them as if engaged; or He is the consenter because, being their witness, He never restrains those engaged in their own workings. He is the bearer: bearing is the holding of their own form by the body, senses, mind and intellect, conjoined and bearing the reflection of consciousness, by reason of the changeless consciousness-Self being their occasion; that holding, being done by the consciousness-Self, makes the Self be called the bearer. He is the enjoyer: like the heat of fire, the consciousness-Self, being by nature constant consciousness, makes the cognitions of the intellect, of the nature of pleasure, pain and delusion, having all objects for their object, appear, arising as if swallowed up by the consciousness-Self and made distinct; and so the Self is called the enjoyer. He is the great Lord: being the Self of all and independent, He is great and a Lord. He is the supreme Self: of the body and the rest, ending with the intellect, falsely imagined by ignorance as the inmost Self, He, marked as the looker-on and the rest, is the supreme Self. By the word 'this' too, 'the supreme Self within', He is told in scripture. Where is He? In this body, the Puruṣa higher than the unmanifest, the one who will be spoken of, 'but the supreme Puruṣa is another, called the supreme Self' (Gītā 15.17). That Self, of the character described, set forth at 'know the field-knower as Me' (Gītā 13.2), is now explained and rounded off.
