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.
Let us put forth all our energies to acquire that which never fails -- our spiritual perfection. If we have true yearning for realization, we must struggle, and through struggle growth will come. We shall make mistakes, but they may be angels unawares.
-Swami Vivekananda
