The Chandogya Upanishad forms the last chapter of the Chandogya Brahmana of the Sama Veda . It is the second largest of the major Upanishads, next only to the Brhadaranyaka Upanishad. Shankara held this Upanishad in great esteem and quoted from it in his bhasya of the Brahma Sutras .
This translation by Swami Lokeswarananda includes the Devanagari script, Roman transliteration, word for word meaning, English translation and notes based on Shankara's commentary. In interpreting the text, the commentary of Sri Sankara has been systematically followed, mainly in the light of the Gloss by Anandagiri.
This is not an easy scripture to read or study, but is nonetheless an important scripture.
