In the brilliant lecture which comprises this book the author stresses on the need to make our spiritual life all-comprehensive. Spirituality should not be narrowed down to morning and evening prayer sessions alone. True spirituality encompasses the whole gamut of human life, our every movement, our every breath. The author shows us the different ways to attain such a totally spiritualized life.
The important thing is how much less you think of the body, of yourself as matter -- as dead, dull, insentient matter; how much more you think of yourself as shining immortal being. The more you think of yourself as spirit, the more eager you will be to be absolutely free from matter, body and senses. This is the intense desire to be free.
-Swami Vivekananda
