India is the home of religion, philosophy and spirituality. Every age, she provides the world with armies of spiritual masters. The beauty of the Indian philosophy is the grand unification of a Metaphysical God who is the Absolute Reality and the substratum of all existence, and a Personal God who is the basis of all morality, ethics and the inspiration to lead a meaningful life. Amongst those Indian philosophers who accepted the separation of mind and body and argued for the existence of the soul, there was considerable dedication to the scientific method and to developing the principles of deductive and inductive logic. As keen observers of nature and the human body, India's early scientist/philosophers studied human sensory organs, analysed dreams, memory and consciousness. The best of them understood dialectics in nature-they understood change, both in quantitative and qualitative terms-they even posited a prototype of the modern atomic theory. The novelty of this book consists of the fact that it introduces the reader to the basic of Indian philosophers and their contribution in Indian philosophy.
