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 human soul has sojourned in lower and higher forms, migrating from one to another according to the samskaras or impressions, but it is only in the highest form as a human being that it attains to freedom.
-Swami Vivekananda
