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.
My name should not be made prominent. It is my ideas that I want to see realized. The disciples of all the prophets have always inextricably mixed up the ideas of the Master with person, and at last killed the ideas for the person.The disciples of Sri Ramakrishna must guard against doing the same thing. Work for the idea, not the person.
-Swami Vivekananda
