This book is comprised of lectures and talks of Swami Prabhavananda on spiritual life. The Swami had an extraordinary ability to make even the most subtle of enigmatic ideas exciting and comprehensible. He contributed a great deal to the understanding of Vedanta in the West and also facilitated a better understanding of all the religions of the world.
Be strong! Don't talk of ghosts and devils. We are the living devils. The sign of life is strength and growth. The sign of death is weakness. Whatever is weak, avoid! It is death. If it is strength, go down into hell and get hold of it! There is salvation only for the brave.
-Swami Vivekananda
