Here we stand, and our eyes look forward sometimes miles ahead. Man has been doing that since he began to think. He is always looking forward, looking ahead. He wants to know where he goes, even after the dissolution of his body. Various theories have been propounded, system after system has been brought forward to suggest explanations. Some have been rejected, while others have been accepted, and thus, it will go on, so long as man is here, so long as man thinks. There is some truth in each of these systems.
There is a good deal of what is not truth in all of them. I shall try to place before you the sum and substance, the result, of the inquiries in this line that have been made in India. I shall try to harmonise the various thoughts on the subject, as they have come up from time to time among Indian philosophers. I shall try to harmonise the psychologists and the metaphysicians, and, if possible, I shall harmonise them with modern scientific thinkers also.
