The control of the mind is not a problem peculiar to religious aspirants; people in all walks of life need to control their minds if they are to succeed in their respective vocation. No fundamental work for the uplift of the individual or of the community can ever be done without the mind being controlled. This book, which sets forth the teachings of Vedanta and Yoga on the nature of the mind and ways of controlling it, is meant for one and all.
The greatest help to spiritual life is meditation. In meditation we divest ourselves of all material conditions and feel our divine nature. We do not depend upon any external help in meditation.
-Swami Vivekananda
