In the pages of this book, one comes across a brilliant exposition of the philosophy of Vedanta and its practice through the method of inquiry and discrimination. These lectures were delivered by Swami Vivekananda in London and New York. The great Swamiji's exposition of a subject so abstruse in a style that makes its comprehension easy even for an ordinary man is nothing short of a miracle. One of the best books dealing with the path of discrimination for attaining the summum bonum of human life and hence very important, not only for the seekers of truth but also for the academicians and students of Vedanta.
