Among Hindus there is a custom, a custom which still exists, that when a marriage is contemplated a Brahmin is consulted, a special priest, and he comes with his books of horoscopes. And after he has made his calculations he decides whether the marriage can take place or not. But in reality the drawing of the horoscopes is an excuse. He is a psychologist, and he considers the question whether the two who are to be married have the same qualities.
