1897. As the basis or receptacle, so to speak, for a mental image, bodily and worldly elements are of service to spirits; earthly elements, such as the meanings of pictures or words, to the angels of the inward heaven; spiritual elements to the angels of the very inward heaven; and heavenly ones to the angels of the innermost heaven. How these ascend by steps, and also by interactions, I suppose no one of mortals understands. Many points, therefore, must be understood before anyone can comprehend even a general idea of angelic languages. 1748, 25 April.
