Brihadaranyaka Upanishad

The Brihadaranyaka Upanishad is estimated to have been composed about 7th-6th century BCE, excluding some parts estimated to have been composed after the Chandogya Upanishad. The Sanskrit language text is contained within the Shatapatha Brahmana, which is itself a part of the Shukla Yajur Veda.

The Brihadaranyaka Upanishad is a treatise on Ātman (Self), includes passages on metaphysics, ethics and a yearning for knowledge that influenced various Indian religions, ancient and medieval scholars, and attracted secondary works such as those by Adi Shankara and Madhvacharya.
