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.'
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
