The seekers of Truth were well-read and committed to the spiritual path in spite of their worldly involvements. They included all age-groups from teenage to ton age! Their commitment and intense longing for the Truth - that inspired me! The scheme of thought presentation had been to devote first few minutes for the recapitulation followed by the next topic in the Upanishad for loud thinking. I felt this as a necessity for every seeker to be reminded of the subjective approach during the study and avoid objectification of the Self. This will be evident when repetition will be observed by the reader every now and then. This is called as abhyasa in technical terms. I was extremely thrilled while editing the pages as if it was a new revelation to me! All the non-English words and names are in Italics for easy comprehension. The equivalent of the Sanskrit words in English is given initially when the word is first introduced. We have followed the commentary of Bhagawan Shankaracharya in letter and spirit to understand the secrets revealed in the text. Modern day examples were found suitable to indicate and emphasise the point made by the great Master. Although we have followed His commentary, the book is presented in the form of talks and not as a word to word meaning and commentary. Hence the title - Contemplation on Taittiriya Upanishad. The thought-wise mantras and translations are appended at the end of the book. The untiring labor and efforts put by Chaity Biswas and Savita Nagananda deserve Self-realization!
