The ancient seers of India realized the highest non-dual Truth and thus attained to unity in the religious field; they succeeded in bringing religion to the rank of a perfect and complete science. The methods adopted by them to come to this result were the same as those followed by all the sciences of the present day. This book discusses how the philosophers of India applied these rational methods in coming to their respective discoveries, thus establishing the scientific character of Indian philosophy and religion. The book chiefly makes a comparative study of Samkhya, Vedanta and other systems of thought.
Those who die, merely suffering the woes of life like cats and dogs, are they human beings? The worthy are those who, even when agitated by the sharp interaction of pleasure and pain, are discriminating and, knowing them to be of an evanescent nature, become passionately devoted to the Atman. This is all the difference between human beings and animals.
-Swami Vivekananda
