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.
Arcana Coelestia # 6284
6284. 'And the name of my fathers Abraham and Isaac' means, and the essential nature of internal goodness and truth. This is clear from the meaning of 'the name' as the essential nature, as immediately above in 6283; and from the representation of 'Abraham and Isaac' as internal goodness and truth, dealt with above in 6276. Internal goodness and truth must be present within external goodness and truth if the latter are to be goodness and truth. For as stated above in 6275, the external is merely something that provides an outward form in which the internal can exist and lead a life in accord with what flows into it from the Lord. And the internal too is merely something providing an outward form when considered in relation to what is supreme, namely the Lord. He is the Source of all life, and things below Him are forms that are merely receivers of life, ranged by degrees in order down to the last and lowest, which is the body.
