This book forms a companion volume to the Swami's Universal Prayers. In the Introduction a detailed and systematic account of the theory and practice of spiritual life is given. The main body of the book containing Sanskrit texts and their English translations, presents a large number of important scriptural passages through which the ancient sages and seers of India enlighten us on ethics, philosophy and practice of meditation.
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
