What does it mean "to kill the Self?" How can the immortal Soul ever be destroyed? It cannot be destroyed, it can only be obscured. Those who hold themselves under the sway of ignorance, who serve the flesh and neglect the Atman or the real Self, are not able to perceive the effulgent and indestructible nature of their Soul; hence they fall into the realm where the Soul light does not shine. Here the Upanishad shows that the only hell is absence of knowledge. As long as man is overpowered by the darkness of ignorance, he is the slave of Nature and must accept whatever comes as the fruit of his thoughts and deeds. When he strays into the path of unreality, the Sages declare that he destroys himself; because he who clings to the perishable body and regards it as his true Self must experience death many times. IV That One, though motionless, is swifter than the mind. The senses can never overtake It, for It ever goes before. Though immovable, It travels faster than those who run. By It the all-pervading air sustains all living beings. This verse explains the character of the Atman or Self. A finite object can be taken from one place and put in another, but it can only occupy one space at a time. The Atman, however, is present everywhere; hence, though one may run with the greatest swiftness to overtake It, already It is there before him. Even the all-pervading air must be supported by this Self, since It is infinite; and as nothing can live without breathing air, all living things must draw their life from the Cosmic Self. V It moves and It moves not. It is far and also It is near. It is within and also It is without all this. It is near to those who have the power to understand It, for It dwells in the heart of every one; but It seems far to those whose mind is covered by the clouds of sensuality and self-delusion. It is within, because It is the innermost Soul of all creatures; and It is without as the essence of the whole external universe, infilling it like the all-pervading ether. VI He who sees all beings in the Self and the Self in all beings, he never turns away from It (the Self). VII He who perceives all beings as the Self for him how can there be delusion or grief, when he sees this oneness (everywhere)? He who perceives the Self everywhere never shrinks from anything, because through his higher consciousness he feels united with all life. When a man sees God in all beings and all beings in God, and also God dwelling in his own Soul, how can he hate any living thing? Grief and delusion rest upon a belief in diversity, which leads to competition and all forms of selfishness. With the realization of oneness, the sense of diversity vanishes and the cause of misery is removed. VIII He (the Self) is all-encircling, resplendent, bodiless, spotless, without sinews, pure, untouched by sin, all-seeing, all-knowing, transcendent, self-existent; He has disposed all things duly for eternal years.
