“There is a man I know who was carried out of himself in Christ, fourteen years since; was his spirit in his body? I cannot tell. Was it apart from his body? I cannot tell; God knows. This man, at least, was carried up into the third heaven. I can only tell you that this man, with his spirit in his body, or with his spirit apart from his body, God knows which, not I, was carried up into Paradise, and heard mysteries which man is not allowed to utter.” (II Corinthians xii, 2-4)
