The author most convincingly establishes the fact that, 'however animal the expression of the nature of an ordinary man of the world may be, his soul is still the image of the Divinity which holds potentially in its bosom all divine powers and all blessed qualities.'
Understanding human nature is the highest knowledge, and only by knowing it can we know God. It is also a fact that the knowledge of God is the highest knowledge, and only by knowing God can we understand human nature.
-Swami Vivekananda
