If we turn to Islam, we find that Mohammed’s revelations all came from the subconscious sphere. To the question in what way he got them—
“Mohammed is said to have answered that sometimes he heard a knell as from a bell, and that this had the strongest effect on him; and when the angel went away, he had received the revelation. Sometimes again he held converse with the angel as with a man, so as easily to understand his words. The later authorities, however, … distinguish still other kinds. In the Itgân (103) the following are enumerated: 1, revelations with sound of bell, 2, by inspiration of the holy spirit in M.’s heart, 3, by Gabriel in human form, 4, by God immediately, either when awake (as in his journey to heaven) or in dream. … In Almawâhib alladunîya the kinds are thus given: 1, Dream, 2, Inspiration of Gabriel in the Prophet’s heart, 3, Gabriel taking Dahya’s form, 4, with the bell-sound, etc. , 5, Gabriel in propriâ personâ (only twice), 6, revelation in heaven, 7, God appearing in person, but veiled, 8, God revealing himself immediately without veil. Others add two other stages, namely: 1, Gabriel in the form of still another man, 2, God showing himself personally in dream.”
In none of these cases is the revelation distinctly motor. In the case of Joseph Smith (who had prophetic revelations innumerable in addition to the revealed translation of the gold plates which resulted in the Book of Mormon), although there may have been a motor element, the inspiration seems to have been predominantly sensorial. He began his translation by the aid of the “peep-stones” which he found, or thought or said that he found, with the gold plates—apparently a case of “crystal gazing.” For some of the other revelations he used the peep-stones, but seems generally to have asked the Lord for more direct instruction.
