I have great pleasure in complying with the request of the friends of the late Swami Rama Tirtha and writing a brief introduction to the series of lectures contained in this book. The name of swami Rama is one which I have learnt to honour through residence in the Punjab where his chief influence was felt. Again and again I have seen faces light up at the mention of his name, and men have told me how much they owed to him. He came at a time when a deep unsettlement was taking place in the minds of educated Indian students with regard to religious truth, and when the claims of the material world were becoming too absorbing. The training in Western Sciences, divorced as it is in Government institutions from religious culture, inevitably led to an indifference to religion altogether.
