RAS question
The Upanishadic concept 'Tat Tvam Asi' appears in:
Correct answer: (A) Chandogya Upanishad.
The Upanishadic expression "Tat Tvam Asi" appears in the sixth chapter of the Chandogya Upanishad, where Uddalaka Aruni teaches Shvetaketu about the relation between the individual and the Absolute.
Explanation
"Tat Tvam Asi" belongs to the Chandogya Upanishad. Britannica identifies it as a famous Hindu expression of the relationship between the individual and the Absolute, repeatedly stated in the sixth chapter as Uddalaka Aruni instructs his son on brahman, the supreme reality. This matches the standard exam explanation: Uddalaka Aruni teaches Shvetaketu that the individual soul is not separate from the universal soul. The option is therefore not asking for a general Upanishadic theme, but for the specific textual location of a major Vedantic formula.
Why the other options are wrong
- (B) Mundaka Upanishad is associated here with "Satyameva Jayate", not with the teaching "Tat Tvam Asi".
- (C) Isha Upanishad is described here as discussing God's omnipresence, so it does not match the cited location of "Tat Tvam Asi".
- (D) Brihadaranyaka Upanishad is linked here with "Aham Brahmasmi", whereas "Tat Tvam Asi" is placed in the Chandogya Upanishad.
Concept
This tests the Ancient Indian History syllabus area on Upanishadic ideas and their textual associations. RAS repeats such pairings because short philosophical formulae are often asked through their source texts.
