Question

Upanishads are written on which topic???​

Answer 1

Answer:

Atman is the predominantly discussed topic in the Upanishads, but they express two distinct, somewhat divergent themes. Younger Upanishads state that Brahman (Highest Reality, Universal Principle, Being-Consciousness-Bliss) is identical with Atman, while older upanishads state Atman is part of Brahman but not identical.

Answer 2

Answer:

The Upanishads are treatises on Brahman-knowledge, that is knowledge of Ultimate Hidden Reality, and their presentation of philosophy presumes, "it is by a strictly personal effort that one can reach the truth".
