Synopsis This twin volume book is designed to acquaint the readers with the basic principles enunciated by the great religions of the world-Santhan Dharma (Hinduism), Buddhism, Jainism, Sikhism and Islam as interpreted and expanded upon by the Ansavtars, Prophets, Saints and Sages who appeared at different cycles of time. These volumes have been embellished with a carefully prepared glossary which inquisitive seekers and readers of religion and philosophy shall find of abiding interest and help. The readers will particularly appreciate the systematic classification and simple language treating them to the secluded, sometimes secret, accounts of life journeys of these Sages, Saints and Mystics through a realm which is denied to most of us.
