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.
We must have friendship for all; we must be merciful toward those that are in misery; when people are happy, we ought to be happy; and to the wicked we must be indifferent. These attitudes will make the mind peaceful.
-Swami Vivekananda
