Although the tongue of God is continually speaking through all things, yet in order to speak to the deaf ears of many among us, it is necessary for Him to speak through the lips of man. He has done this all through the history of man, every great teacher of the past having been this guiding spirit living the life of God in human guise. In other words, their human guise has been various coats worn by the same being, who only appeared to be different in each. Shiva, Buddha, Rama, Krishna on the one side; Abraham, Moses, Jesus, Muhammad on the other; and many more, known or unknown to history, have always been in reality one and the same person.
