It appears at the end of a section, and is repeated at the end of the subsequent sections as a refrain: In ChU.6.8.12 it appears as follows: Etymology and translation Tat Tvam Asi (Devanagari: तत्त्वमसि, Vedic: tát tvam ási) is traditionally translated as "Thou art that", "That thou art", "That art thou", "You are that", "That you are", or "You're it"; although according to Brereton and others the proper translation would be "In that way [=thus] are you, Svetaketu", or "that's how you are": tat - "it", "that"; or alternatively "thus", "in that way", "that's how". tvam - you, thou asi - are, 'art' In Ch.U.6.8.7 tat refers to Sat, "the Existent", Existence, Being. Sat, "the Existent", then is the true essence or root or origin of everything that exists, and the essence, Atman, which the individual at the core is. As Shankara states in the Upadesasahasri: While the Vedanta tradition equates sat ("the Existent") with Brahman, as stated in the Brahma Sutras, the Chandogya Upanishad itself does not refer to Brahman. According to Brereton, followed by Patrick Olivelle and Wendy Doniger, the traditional translation as "you are that" is incorrect, and should be translated as "In that way [=thus] are you, Svetaketu." That, then, in ChU.6.8.12 refers to "the very nature of all existence as permeated by [the finest essence]", and which is also the nature of Svetaketu. Lipner expresses reservations on Brereton's interpretation, stating that it is technically plausible, but noting that "Brereton concedes that the philosophical import of the passage may be represented by the translation 'That you are', where tat as 'that' would refer to the supreme Being (sat/satya)." Interpretation Major Vedantic schools offer different interpretations of the phrase: Advaita - absolute equality of 'tat', the Ultimate Reality, Brahman, and 'tvam', the Self, Atman. Shuddhadvaita - oneness in "essence" between 'tat' and individual self; but 'tat' is the whole and self is a part. Vishishtadvaita -'tvam' denotes the Jiva-antaryami Brahman while 'tat' refers to Jagat-Karana Brahman. Dvaitadvaita - equal non-difference and difference between the individual self as a part of the whole which is 'tat'. Dvaita of Madhvacharya - Sa atmaa-tat tvam asi in Sanskrit is actually Sa atma-atat tvam asi or 'Atma (Self), thou art, thou art not God”. In refutation of Mayavada (Mayavada sata dushani), text 6, tat tvam asi is translated as "you are a servant of the Supreme (Vishnu)". Acintya Bheda Abheda
