Why read this?

Chandogya contains some of the most influential teaching stories in Indian thought, including the teaching summed up in 'tat tvam asi' (you are that), which Vedanta schools interpret in sharply different ways. Its dialogues show teachers using everyday examples, clay, salt, a seed, to make abstract ideas concrete.

The frame story

In the sixth chapter the young Shvetaketu returns home proud after twelve years of study. His father Uddalaka Aruni asks whether he has learned that by which the unheard becomes heard. Through examples such as clay and its products, a tiny banyan seed and salt dissolved in water, he teaches that one subtle Being underlies everything, ending each lesson with the refrain that Shvetaketu is that. Later chapters include Narada learning from Sanatkumara, and Indra and the demon Virochana learning from Prajapati.

Questions it answers

?What is the one thing by knowing which everything is known?
?What is the relation between the individual and the whole?
?What is the real Self?

Key teachings

Editorial overview

In the beginning was Being

Uddalaka teaches that in the beginning there was Being (sat) alone, one without a second, from which the world emerged.

Clay and its forms

Just as by knowing one lump of clay all things made of clay are known, names and forms being only modifications, so by knowing Being all is known.

You are that

The refrain 'tat tvam asi' links the individual to that subtle Being. Advaita reads it as strict identity; Vishishtadvaita as the Lord indwelling the soul as its inner self; Dvaita, through Madhva's reading, as similarity or dependence rather than identity.

All this is Brahman

The Shandilya teaching in chapter 3 asks one to meditate on all this as Brahman and on the Self within the heart as smaller than a grain yet greater than the worlds.

The Self is not the body

In chapter 8 Indra and Virochana learn from Prajapati; Virochana settles for the body as the Self, while Indra keeps returning with doubts until he is taught a deeper Self.
