What is Brahman? What is its relationship to Atman? What is an individual's place in the cosmos? Is a personalised god and ritualistic worship the only path to attain moksha? Does caste matter when a human is engaging with the metaphysical world? The answers to these perennial questions sparkle with clarity in this seminal account of a man and a saint, who revived Hinduism and gave to Upanishadic insights a rigorously structured and sublimely appealing philosophy.Jagad Guru Adi Shankaracharya (788-820 CE) was born in Kerala and died in Kedarnath, traversing the length of India in his search for the ultimate truth. In a short life of thirty-two years, Shankaracharya not only revived Hinduism, but also created the organisational structure for its perpetuation through the mathas he established in Sringeri, Dwaraka, Puri and Jyotir Mathas.Adi Shankaracharaya: Hinduism's Greatest Thinker is a meticulously researched and comprehensive account of his life and philosophy. Highly readable, and including a select anthology of Shankaracharya's seminal writing, the book also examines the startling endorsement that contemporary science is giving to his ideas today. A must read for people across the ideological spectrum, this book reminds readers about the remarkable philosophical underpinning of Hinduism, making it one of the most vibrant religions in the world.
