I SHALL not Endeavour to give, in this single lecture, any general description of Indian Religions. Nor do I propose to make any appreciable addition to the vast heap of facts and anecdotes, fables and folklore, that have been already collected in support of different theories regarding the origin of myth, ritual, primitive worships, and rudimentary belief. My present purpose is to draw attention, briefly, to the particular importance of India as a field of observation and research in identifying and tracing through connected stages the growth and filiations of some of the principal ideas that undoubtedly lie at the roots of Natural Religion.
