The question, how does a prophet know of this? may be answered by saying that the soul of the prophet is like a fruit which by its weight touches the ground; it has not dropped on to the earth like other fruits; it is still connected with the branch to which it is attached, the branch which droops through all the planes of existence; and so he, in his experience of the different planes, so to speak, touches all worlds. It is this mystery which is hidden behind the life of the prophet. It is through this branch that the fruit is connected with the stem. Therefore, though on earth, he calls aloud the name of God. While to many God is an imagination, to him God is the reality.
