born, never dies, part of that which existed before the universe was formed from "brooding heat". Sun rests in it, gods rest in it, all nature rests in it, it is everywhere, it is in everything. To understand the eternal nature of one's Self is to feel calmness, inner peace, patience and freedom regardless of the circumstances one is in, affections or threats one faces, praises or insults one is subjected to. Anyone who runs after sensory-impressions, gets lost among them just like water flows randomly after rainfall on mountains, state verses 2.4.14 and 2.4.15 of the Katha Upanishad; and those who know their Self and act according to its Dharma remain pure like pure water remains pure when poured into pure water. There is no plurality and separateness between the essence (Atman) of I and others, between the essence of nature and spirit, asserts Katha Upanishad in verses 2.4.10 and 2.4.11.

This Self is worshipped by all the gods. Body dies, Self doesn't. In verses 2.5.6 and 2.5.7, the Katha Upanishad discusses what happens to the Self after death, stating a variant of the premise of Karma theory that underlies major Indian religions, The Self is always awake and active, while one is asleep, shaping wishful dreams. It is one with Brahman. It is
