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.
If there is no strength in body and mind, the Atman cannot be realized. First you have to build the body by good nutritious food -- then only will the mind be strong.
-Swami Vivekananda
