The Great Epic of the Bhārata dynasty 6.24.23

6.24.23

nainaṃ chindanti śastrāṇi nainaṃ dahati pāvakaḥ |
na cainaṃ kledayantyāpo na śoṣayati mārutaḥ || 23 ||

He who thinks it (the soul) to be the slayer and he who thinks it to be the slain, both of them know nothing; for it neither slays nor is slain. It is never born, nor doth it ever die; nor, having existed, will it exist no more. Unborn, unchangeable, eternal, and ancient, it is not slain upon the body being perished. That man who knoweth it to be indestructible, unchangeable, without decay, how and whom can he slay or cause to be slain? As a man, casting off robes that are worn out, putteth on others that are new, so the Embodied (soul), casting off bodies that are worn out, entereth other bodies that are new. Weapons cleave it not, fire consumeth it not; the waters do not drench it, nor doth the wind waste it. It is incapable of being cut, burnt, drenched, or dried up. It is unchangeable, all-pervading, stable, firm, and eternal. It is said to be imperceivable, inconceivable and unchangeable. Therefore, knowing it to be such, it behoveth thee not to mourn (for it). Then again even if thou regardest it as constantly born and constantly dead, it behoveth thee not yet, O mighty-armed one, to mourn (for it) thus. For, of one that is born, death is certain; and of one that is dead, birth is certain. Therefore. it behoveth thee not to mourn in a matter that is unavoidable. All beings (before birth) were unmanifest. Only during an interval (between birth and death), O Bharata, are they manifest; and then again, when death comes, they become (once more) unmanifest.
