Aitareya UpanishadThe Aitareya Upanishad belongs to the Rig Veda and traces creation from the supreme Self, the entry of consciousness into the human body, and the realisation that the Atman alone is Brahman. Brief but profound, it is one of the principal Upanishads commented on by Shankara and remains a foundational text of Advaita Vedanta.Book link ↗
