This Upanishad holds an important position in the age-old spiritual tradition of India. It forms the last chapter of the Shukla Yajur Veda Samhita. The message of this small Upanishad, having only eighteen verses, is as profound as it is comprehensive. It proclaims the divinity of man and nature, and the spiritual oneness of all existence. It asserts that God is enveloping everything, indeed, that God is in everything. It can be said that this Upanishad provides the fundamental theme of Vedantic thought.
This Lokeswarananda edition contains the original Upanishad in Devanagri script, transliteration, and English translation with notes based on Sri Shankara.
