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.
Nature grinds all of us. Keep count of the ounce of pleasure you get. In the long run, nature did her work through you, and when you die your body will make other plants grow. Yet we think all the time that we are getting pleasure ourselves. Thus the wheel goes round.
-Swami Vivekananda
