1786. That "a vision" denotes inmost revelation, which is that of perception, may be seen from the nature of visions, which take place in accordance with the man's state. To those whose interiors are closed, a vision is very different from what it is to those whose interiors are open. For example: when the Lord appeared to the whole congregation in Mount Sinai, the appearing was a vision that was different to the people from what it was to Aaron, and that was different to Aaron from what it was to Moses; and again, visions were different to the prophets from what they were to Moses. There are many kinds of visions, concerning which, of the Lord's Divine mercy hereafter. The more interior the visions, the more perfect they are. With the Lord they were the most perfect of all; because He then had perception of all things in the world of spirits and in the heavens, and also had immediate communication with Jehovah. This communication is represented, and in the internal sense is signified, by the vision in which Jehovah appeared to Abram.
