"[I]t must be borne in mind that Hinduism is far more than a mere form of theism resting on Brāhmanism. It presents for our investigation a complex congeries of creeds and doctrines which in its gradual accumulation may be compared to the gathering together of the mighty volume of the Ganges, swollen by a continual influx of tributary rivers and rivulets, spreading itself over an ever-increasing area of country and finally resolving itself into an intricate Delta of tortuous steams and jungly marshes. … The Hindu religion is a reflection of the composite character of the Hindus, who are not one people but many. It is based on the idea of universal receptivity. It has ever aimed at accommodating itself to circumstances, and has carried on the process of adaptation through more than three thousand years. It has first borne with and then, so to speak, swallowed, digested, and assimilated something from all creeds."
