Every cult of mystics has used certain names. There are certain names in the cult of the Hindus, under which they recognize certain masters. We find them also in the Semitic races, mentioned in the Bible, the Kabala, and the Qur'an. Naturally, the human mind has its limitations. If we had no limitations we should be perfect. So it has always been that man has recognized as masters only those who are found in his own tradition. He only recognizes the spirituality or greatness or blessedness of those whose names he finds in his own tradition. In the Hebrew tradition there are the names of Abraham and Moses; in the Christian tradition there is the name of Jesus Christ, and after him those of the saints; in the tradition of Islam there are other names again, Mohammed and many Muslim saints; and in India there are, for instance, Rama, Shiva, Vishnu, and Krishna. And as there was little means of communication in ancient times, it was only natural that the tradition of one country should not be known to the others, and that it should become corrupted as it passed to another.
