The fact that Hinduism is something larger and more comprehensive than what we call a religion is one reason why it contains much of dubious moral value. It is analogous not to Christianity but to European civilization which produces side by side philanthropy and the horrors of war, or to science which has given us the blessings of surgery and the curse of explosives. There is a deep-rooted idea in India that a man's daily life must be accompanied by religious observances and regulated by a religious code, by no means of universal application but still suitable to his particular class. An immoral occupation need not be irreligious: it simply requires gods of a special character. Hence we find Thugs killing and robbing their victims in the name of Kali. But though the Hindu is not at ease unless his customs are sanctioned by his religion, yet religion in the wider sense is not bound by custom, for the founders of many sects have declared that before God there is no caste. A Hindu may devote himself to religion and abandon the world with all its conventions, but if like most men he prefers to live in the world, it is his duty to follow the customs and usages sanctioned for his class and occupation. Thus as Sister Nivedita has shown in her beautiful writings, cooking, washing and all the humble round of domestic life become one long ritual of purification and prayer in which the entertainment of a guest stands out as a great sacrifice. But though religion may thus give beauty and holiness to common things, yet inasmuch as it sanctifies what it finds rather than prescribes what should be, it must bear the blame for foolish and even injurious customs. Child marriages have nothing to do with the creed of Hinduism, yet many Hindus, especially Hindu women, would feel it irreligious, as well as a social disgrace, to let a daughter become adult without being married. A comparison of Indian Mohammedans and Hindus suggests that the former are more warlike and robust, the latter more intellectual and ingenious. The fact that some Mohammedans belong to hardy tribes of invaders must be taken into account but Islam deserves the credit of having introduced a simple and fairly healthy rule of life which does not allow every caste to make its own observances into a divine law. Yet it would seem that the medical and sanitary rules of Hinduism deserve less abuse than they generally receive. Col. King, Sanitary Commissioner of the Madras Presidency, is quoted as saying in a lecture[84]: "The Institutes of Vishnu and the Laws of Manu fit in excellently with the bacteriology, parasitology and applied hygiene of the West. The hygiene of food and water, private and public conservancy, disease suppression and prevention, are all carefully dealt with."
