-Chandogya upanishad, VI.VIII ...
Chandogya Upanishad is also one of the oldest ones and perhaps the best known. It belongs to Saamveda, the veda with metre. It has many very interesting passages in which we learn
- of the knowledge that Kshatriyas had but Brahmins did not,
- of Satyakama's story about how its not your birth that decides if you are a Brahmin,
- of Aruni's statement about the origin of the universe from sat which in the same breath challenges another theory of origin,
