This story illustrates what has happened in the lives of the messengers, especially of Jesus Christ and Mohammad, though the terms Father, Son, Brother, are merely metaphorical. There has been one Teacher only, and He alone will be. All the names which the world has fought over are His names, and all the physical forms that have won the adoration of the truth-seeking world are His forms. Therefore, though the foolish reject the message, there are wise ones who accept it.
