For over forty years Swami Chinmayananda was one of the leading interpreters and teachers of the Hindu philosophical system of Advaita Vedanta, which establishes with exact logic the identity of the self (Atman) with the infinite (Brahman). Through a variety of institutions and methods particularly the jñāna yajñas, rituals of truth, he worked to rejuvenate Hinduism by making hitherto inaccessible insights of the Upanishads and the Bhagavad - gita available to masses. Thereby, he was instrumental in bringing the wisdom of the Hindu heritage to everyone, regardless of caste, creed, gender, religion or nationality. This is the first biography of Swami Chinmayananda and retraces his journey from his childhood in Kerala, through his carefree college days and rebellion against British imperialism, then his spiritual tutelage under Swami Shivananda and Swami Tapovanam. An account is given detailing the growth of a worldwide movement under his guidance. Included are conversations with him on different subjects that demonstrate his sharp intellect, deep wisdom and quick wit. He is undoubtedly one of the outstanding and influential figures in the modern history of India.
