In clear and persuasive language, the author has sketched the four great paths to God-realization, namely, Karma yoga, Bhakti yoga, Raja yoga and Jnana yoga.
Let each one of us pray day and night for the downtrodden millions, who are held fast by poverty, priestcraft, and tyranny. Pray day and night for them. I care more to preach religion to them than to the high and the rich. I am no metaphysician, no philosopher, nay, no saint. But I am poor and I love the poor.
-Swami Vivekananda
