Ever since the great advaitin Sankara wrote his famous commentaries on the ten major Upanisads, what other commentators have done so far is elaborate on Sankara's ideas. Deviating from his line of thought seems to be considered a sort of sin. We, on the other hand, felt it imperative to take a fresh look at the Upanisads in view of all the modern developments of thought in science as well as philosophy. We had the good fortune of getting sufficient guidance from our guru, Nataraja Guru. Guru Nitya Chaitanya Yati took up the onerous task of writing commentaries on the two largest Upanisads, Brhadaranyaka and Chandogya. He asked me to comment on the rest on the ten. Incidentally he had already written his commentaries on the Isa and Mandukya Upanisads; so I had to deal with only six Upanisads. Of course, my commentary on the Isa Upanisads had already formed part of my book Basic Lessons on India's Wisdom, a textbook for beginners in Vedanta. Guru Nitya did complete the commentary on the Brhadaranyaka in three volumes which were published by Messers D. K. Printworld. My commentaries on the six Upanisads were written one by one and all were published by the same publishers. Guru Nitya's old age disabilities did not allow him to step the other major task of commenting on Chandogya Upanisad. As it became clear that he would not be able to take up the job, I decided to do it myself.
One of the hurdles I found in entering the essence of the wisdom teaching of the Chandogya Upanisad and the method of presentation it adopts was the relevancy of the first three chapters which apparently deal only with Vedic rituals (Karma-kanda). Sankara's commentary also did not help find a solution to the problem which I felt was a major one. Repeated reading of stanzas and sections, one by one, revealed how the Upanisad pictorially explicates the historical fact that the wisdom section (Jnana-kanda) of the Vedas is an outgrowth of the ritualistic section ( karma-kanda). Such a phenomenon in the history of culture is known as dialectical revaluation, a concept very dear to, and widely made us of, by Nataraja Guru in his writings. I have tried my best to clarify the nature of this dialectical revaluation both in the "Introduction," and the commentary. This discovery laid wide open before me the scheme of the development of thought of the present Upanisad, and it made the writing of the commentary with a regular flow very easy.
A group of Gurukula inmates and research scholars was around me to have a detailed discussion on each stanza. Later the commentary was dictated to them in Malayalam. I, then, sitting alone in my room, translated it into English the same day. The Malayalam and English versions of the commentary were thus prepared simultaneously. I am thankful to all those who helped me with ideas during the discussions.
Mrs. Kala Krishnan Remesh of Bangalore and Dr. Peter Oppenheimer of the United States, both long-time Gurukula friends, took much pain editing the book. Both of them did it as a service to the cause of wisdom, particularly as restated by Narayana Guru. Over and above all, it was the clarity of the philosophy of Narayana Guru that shed light on every Mantra of this intricate Upanisad.
Messers D. K. Printworld of New Delhi, from the Very beginning, have shown much interest in publishing these commentaries as well as other books including those of Nataraja Guru and Guru Nitya Chaitanya Yati.
Narayana Guru used to encourage orators on religious matters to give public talks on Upanisads interpreting them independently. This encouragement of the Guru has always been the main inspiring force for writing all these commentaries, sometimes daring to deviate from the already available traditional path.
I offer this commentary as an altar -flower at the feet of Narayana Guru and of my Nataraja Guru, as well as of my predecessor-guru, Guru Nitya Chaitanya Yati.
From the Jacket
Chandogya is the most intriguing of all the Upanisads. It begins with directing the priests of a Soma-yaga to see the hidden wisdom significance in what they perform and recite as a brute ritual. This sublimating of ritualism gradually leads us to perceiving the entire life system as a Yajna held in and performed by Brahman. The next step this perception leads us to is "Sarvam Khalvidam brahma" (everything here indeed is Brahman). Then the enquiry as to what this Brahman is, begins. The answer we arrive at is "tat tvam asi" (That thou art). Finally we realize "atmaivedam sarvam" (atma) indeed is everything here, or myself indeed is everything here). From this self-identity with "everything," with Brahman, we never return to our identity with individuated forms pertaining to the world of becoming.
The present commentary explicates in a lucid way how thinking progresses in this Upanisad, along with unraveling its schematic, structural and dialectical intricacies, both subjective and objective, both universal and particular.
