1786. That 'a vision' means inmost revelation, which is an accompaniment of perception, becomes clear from the nature of visions, in that these take shape each one in accordance with the state of the beholder. A vision appearing to those whose interiors are closed takes an entirely different shape from a vision to those whose interiors are open. For example, when the Lord appeared to the whole congregation on Mount Sinai, that appearing was a vision which was different for the people from what it was for Aaron, and was different for Aaron from what it was for Moses; and a vision for the prophets was different again from what it was for Moses. Many kinds of visions are possible, which will in the Lord's Divine mercy be spoken about later on. Visions are more perfect the more interior they are. With the Lord they were the most perfect of all, because at that time He had a perception of all things in the world of spirits and in the heavens, and had direct communication with Jehovah. This communication is represented, and in the internal sense is meant, by the vision in which Jehovah appeared to Abram.
