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.
All who have actually attained any real religious experience never wrangle over the form in which the different religions are expressed. They know that the soul of all religions is the same and so they have no quarrel with anybody just because he or she does not speak in the same tongue.
-Swami Vivekananda
