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.'
It is always for greater joy that you give up the lesser. This is practical religion -- the attainment of freedom, renunciation. Renounce the lower so that you may get the higher. Renounce! Renounce! Sacrifice! Give up! Not for zero. Not for nothing, but to get the higher.
-Swami Vivekananda
