Synopsis Saints have been born in India in all ages. The list of their names is endless and long. It is difficult to present and give complete account of the spiritual journey of all-them under one cover. For this reason only three to four in each volume have been included. In this volume, the life sketch, the spiritual odyssey and the contribution made to the contemporary society by Lord Mahavira, Gautam Buddha and AdiGuru Sankaracharya have been chronologically and extensively narrated in a lucid manner. Effort has been made to include as much of details about them as possible within the constrain of space. It is hoped that the effort would satisfy readers in their quest for details.
