Many levels of meaning can shape one idea, thus one word or sign, and then be understood together. This is especially apparent from spiritual speech, in which those many levels of meaning shape just one seemingly single and instantaneous mental image, like what has just been said, and what is now being said, about words and meaning, each of which make up just one idea when we are speaking with spirits. So also in other cases. A like idea exists also with people on earth, for when one has read these words, one grasps them in a single mental image. So in other cases. 1748, 15 March.
