171. The nature of the objects that are visible to angels in the heavens cannot be described in a few words. For the most part, they are like things on earth but more perfect in form and more abundant in number. That such things are in the heavens can be confirmed from the things seen by the prophets-as by Ezekiel, in respect of the new temple and the new earth, described from chapter xl. to xlviii, by Daniel from chapter vii. to xii., by John from the first to the last chapter of the Revelation, and by others, as described both in the historical and the prophetical parts of the Word. These things were seen by them when heaven was opened to them, and heaven is said to be opened when the interior sight, which is the sight of man's spirit, is opened. For the things that are in the heavens cannot be seen by the eyes of a man's body, but are seen by the eyes of his spirit. When it seems good to the Lord, these are opened and man is then withdrawn from the natural light in which he is from the senses of the body, and is raised up into a spiritual light in which he is from his spirit. In that light the things that are in the heavens have been seen by me.
