This book serves as an introduction to the six systems of Hindu philosophy. Though these six systems are different in their approaches to the truth, they are unanimous as far as the final goal of humankind is concerned, which is, total eradication of suffering and attainment of state of eternal peace.
If a person who lives in God becomes miserable, what is the use of living in God? What is the use of such a God? Throw such a God overboard into the Pacific Ocean. We do not want such a God!
-Swami Vivekananda
