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.
Truth, purity and unselfishness -- wherever these are present, there is no power below or above the sun to crush the possessor thereof. Equipped with these, one individual is able to face the whole universe in opposition. - Swami Vivekananda
