The speech of an angel or spirit with man is heard by him as audibly as the speech of man with man, yet by himself only, and not by others who stand near; and for the reason that the speech of an angel
or spirit flows first into a man's thought, and by an inner way into his organ of hearing, and thus moves it from within; while the speech of man with man flows first into the air and by an outward
way into his organ of hearing, and moves it from without. Evidently, then, the speech of an angel or spirit with man is heard within him; but as the organs of hearing are thus equally moved, the speech
is equally audible. That the speech of an angel or a spirit flows down from within even into the ear has been made clear to me by the fact that it flows also into the tongue, causing a slight vibration,
but without any such motion as when the man himself by means of the tongue forms the sound of speech into words.
