Adi Sankara's Tattva Bodhah is a preliminary text and it is presented in the form of a dialigue between the Guru and the disciple and clearing all the fundamental questions. 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. Pages 112
