There is a great deal of psychic law which can be traced in such beliefs, and in time such beliefs turn into customs. There is a vast field of knowledge in the beliefs of Indians. India has been a country where beliefs have existed for thousands of years unchanged, and some beliefs have become customs. At first sight an intellectual person who cannot look any further than the surface of things is apt to think that people in India are full of superstitions. Their whole life seems based on them; not only in religion do they have beliefs, but even in their domestic affairs. In their everyday life every move they make, every word they say is in accordance with some underlying belief.
