The human psyche is so composed that most of us, including atheists, at some point of time ask fundamental questions of life. It may begin with 'Why did this happen to me?' Then it goes on to 'Is there God? Who am I? What is the goal of human life? What happens when one dies? Why was the world created? By whom? How?....' In Tattvabodha, Sri Adi Shankaracharya lovingly answers these and many more such questions and introduces the aspiring student to the basic principles of Vedanta - the science of Life. This preliminary text is presented in the form of a dialogue between the Guru and the disciple. The disciple asks with genuine eagerness and the Guru answers with patience, with depth and with precision. Swami Tejomayananda's commentary on this text is illuminating and answers even unasked doubts of the beginner. His exposition, from what it takes to be a seeker to what it takes to make a saint of oneself, is masterly.
