Heaven and Hell # 171
171. There is no way to describe briefly how things look to angels in the heavens. To a considerable extent, they look like the things we see on earth, but they are more perfect in form and also more abundant.
We may conclude that there are things like this in the heavens because of what the prophets saw - for example what Ezekiel saw of the new temple and the new earth as described in chapters 40-48 [of his book], what Daniel describes in his chapters 7-12, what John saw as described from the first through the last chapter of Revelation, along with other visions presented in both the historical and the prophetic books of the Word. They saw things like this when heaven was opened to them, and heaven is said to be opened when our inner sight, the sight of our spirit, is opened. For the things that exist in heaven cannot be seen with our physical eyes, but only with the eyes of our spirit; and when it pleases the Lord, these are opened. At such times we are led out of the natural light that our physical senses are in and raised into the spiritual light in which we dwell because of our spirit. This is the light in which I have seen the things that exist in the heavens.

4791. CORRESPONDENCE WITH THE GRAND MAN - continued
IN THIS SECTION THE CORRESPONDENCE OF TASTE AND OF THE TONGUE, AND ALSO OF THE FACE, WITH THAT GRAND MAN
The tongue provides an entrance leading into both the lungs and the stomach, and so represents a kind of forecourt leading to spiritual things and to celestial ones, to spiritual because it serves the lungs and thereby speech, to celestial because it serves the stomach which supplies nourishment to the blood and the heart. For the lungs correspond to spiritual realities, the heart to celestial ones, see 3635, 3883-3896. All this being so, the tongue corresponds in general to the affection for truth, that is, to those in the Grand Man whose affection is for truth, and after that whose affection is for good which is a product of that truth. People therefore who love the Word of the Lord and wish to gain from it a knowledge of what is good and true belong to that province. Yet they differ from one another, in that some belong to the actual tongue, some to the larynx and trachea, some to the throat, some also to the gums, while others belong to the lips. For not even the smallest part of the human being fails to have a correspondence.
[2] I have been allowed on many occasions to learn by experience that those governed by an affection for truth belong to that province understood in the broad sense. On one occasion they plainly entered my tongue, on another my lips; and I have been allowed to talk to them. I have also noticed that some correspond to the more internal parts of the tongue and lips, others to their more external parts. There are some who have an affection for and receive only exterior truths, not interior ones, though they do not reject them. The operation of these I have felt in the exterior but not the interior parts of my tongue.
