ABSTRACT
The Chandogya Upanisad is the second longest after the Brhadaranyaka, and is close to it in age. It shows a similar concern with ritual - especially with chant, since it belongs to the Samaveda. The Chandogya Upanisad is in eight chapters, called prapathakas, "recitations", each divided into sections and subsections. The text recognizes this composite nature of the chapters by dividing them into parts, marked by an ancient device used in some other Upanisads: a repetition of the last few words. While many dialogues in the Upanisads are between brahmins who are ritual colleagues, some teachers and pupils are not brahmins. Indra gains the favor of Prajapati by performing the duties of a Vedic student, as well as by his understanding; in Vedic thought as in later tradition, right behavior and right understanding go together, both being aspects of satya "truth".
