Parabrahman.

The Upanishads state that the Supreme Brahma is Eternal, Conscious, and Blissful sat-chit-ânanda. The realisation of this truth is the same as being this truth:

• "The One is Bliss. Whoever perceives the Blissful One, the reservoir of pleasure, becomes blissful forever." (Taittiriya Upanishad 2.7.1-2)^{[note 3]}
• "Verily know the Supreme One to be Bliss." (Brihadaranyaka Upanishad 2.9.28)
