In the pages of this book one comes across a brilliant exposition of the philosophy of Vedanta and its practice through the method of enquiry and discrimination. These lectures were delivered by Swami Vivekananda at London and New York. The great Swami's exposition of a subject so abstruse in a style which makes its comprehension easy even for an ordinary man is nothing short of a miracle in English language. 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.
Those who have succeeded in attaching or detaching their minds at will have succeeded in Pratyahara, which means gathering towards, checking the outgoing powers of the mind, freeing it from the thralldom of the senses. When we can do this, we shall really possess character; then alone we shall have taken a long step towards freedom. Before that, we are mere machines.
-Swami Vivekananda
