The author has organized Swami Vivekananda's ideas to develop a holistic approach based on Vedanta to the problem of understanding and quantifying human development in this book.
Nature, body, mind go to death, not we. We neither go nor come. The man Vivekananda is in nature, is born and dies; but the Self we see as Vivekananda is never born and never dies. It is the eternal and unchangeable Reality.
-Swami Vivekananda
