Generally a person dealing with others thinks of the affair more than of the person. Really the person must be the chief object of study, not the affair, for the affair depends upon the person. In the East there is a superstition of a dog or a cat or a horse being lucky or unlucky for the person who possesses it, but the reality of this idea can be most seen in every human being with whom one comes in contact through one's everyday life. He must surely bring something with him, pleasure, displeasure, happiness, unhappiness, good or bad influence.
