11.7.49

kālena hy ogha-vegena bhūtānāṃ prabhavāpyayau /
nityāv api na dṛśyete ātmano 'gner yathārciṣām //

49. By Time rushing on like torrents are brought about the origin and destruction of beings, but these states, though eternal, do not affect Atman, just as only the flames, and not the principle of fire, have a beginning and an end.
