In this book the author discusses the subject of human development in India's post-independent social, economic, and political context. He draws our attention to the subject of man and the problem of inter-human relationship, advocating service as the finest form of inter-human relationship.
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
