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.
If you think that you are bound, you remain bound; you make your own bondage. If you know that you are free, you are free this moment. This is knowledge, knowledge of freedom. Freedom is the goal of all nature.
-Swami Vivekananda
