(2) Where then is the world of the sacrificer? He who does not know this, how can he perform the sacrifice? He only who knows, should perform it .

(10) The Person is all this, sacrifice, penance, Brahman, the highest immortal; he who knows this hidden in the cave (of the heart), he, O friend, scatters the knot of ignorance here on earth.

(4) Verily, he Is the great, unborn Soul, who is this [person] consisting of knowledge among the senses. In the space within the heart lies the ruler of all, the lord of all, the king of all. He does not become gi eater by good action nor inferior by bad action. He is the lord of all, the overlord of beings, the protector of beings. He is the separating dam for keeping these worlds apart. Such a one the Brahmans desire to know by repetition of the Vedas, by sacrifices, by offerings, by penance, by fasting. On knowing him, in truth, one becomes an ascetic (muni). Desiring him only as their home, mendicants wander forth. Verily, because they know this, the ancients desired not off- spring, saying: <c What shall we do with offspring, we whose is this Soul, this home? " They, verily, rising above the desire for sons and the desire for wealth and the desire for worlds, lived the life of a mendicant. For the desire for sons is the desire for wealth, and the desire for wealth is the desire for worlds; for both these are desires. That Soul (Atman) is not this, it is not that (neti, neti}. It is unseizable, for it cannot be seized. It is indestructible, for it cannot be destroyed. It is unattached, for it does not attach Itself. It is unbound. It does not tremble. It is not injured. Him [who knows this] these two do not overcome — neither the thought <c Hence I did wrong," nor the thought " Hence I did right/' Verily, he overcomes them both. What he has done and what he has not done do not affect him.
