Notes on Chandogya Upanishad
Chapter 6 - The crux of the Chandogya Upanishad is found in this chapter wherein the famous Mahavakya - Tat Tvam Asi is declared. Here the Upanishad presents Brahma Vidya (the knowledge of the Supreme Truth) in a drama-dialogue style, as a discussion between the Guru-father, Uddalaka Rishi and his son-disciple, Shvetaketu.
Chapter 7 - This chapter of the Chandogya Upanishad, which is a dialogue between the great sage Sanatkumara and his younger brother, turned disciple, the famous Narada, makes us realise that all knowledge is the play of words alone - nama eva etat. Yet the words of the text have the unique power not only to prepare us but finally awaken us to our true nature, which is Infinite Bliss - Bhumaiva Sukham.
Chapter 8 - This chapter of the Chandogya Upanishad drives home the fact that a state of total fulfillment of desires (satyakama) is attained through Brahmavidya - the knowledge of the ultimate Truth which results in Self-realization whereby one remains untouched by any situation in life.
