तत्त्वमसि
tat tvam asi
THAT THOU ART
— Chāndogya 6.8.7 (and repeated 8 more times in chapter 6)

Central Teaching

The longest narrative-rich Upaniṣad · contains the Sanat-Kumāra → Nārada teaching (Adhyāya 7), the Indra-Virocana story (Adhyāya 8), and the Uddālaka-Śvetaketu dialogue (Adhyāya 6) in which Uddālaka teaches his son the supreme identity 9 times with the seal "tat tvam asi" — That Thou Art. The mahā-vākya of the Sāma-Veda · the most-quoted of the four mahā-vākyas across Advaita literature. Krishna's declaration in BG 10.22 "vedānāṁ sāma-vedo 'smi" makes Chāndogya the Krishna-anchor among Upaniṣads.

Key Śloka

ऐतदात्म्यमिदं सर्वं तत्सत्यं स आत्मा तत्त्वमसि श्वेतकेतो।

aitad-ātmyam idaṁ sarvaṁ · tat satyaṁ · sa ātmā · tat tvam asi · śvetaketo

"All this has THAT for its Self · THAT is Truth · THAT is the Self · TAT TVAM ASI (That Thou Art), O Śvetaketu."

— Chāndogya 6.8.7 (repeated in 6.9, 6.10, 6.11, 6.12, 6.13, 6.14, 6.15, 6.16)

🪷 Krishna-Tattva Connection

Krishna explicitly identifies with Sāma-Veda in BG 10.22 — making Chāndogya His own scripture. The mahā-vākya "tat tvam asi" is enacted in BG 6.29 (the yogī sees the same Self in all beings · ātmaupamyena sarvatra samaṁ paśyati). The Vidhyamitra page /vibhuti/sama-veda is the cross-anchor.
