269. It can be deduced that this happens in heaven as a whole from the similar phenomena in each community in heaven. For each community is a heaven on a smaller scale, also resembling a person. (On this see my book HEAVEN AND HELL, 41-87.) In every community in heaven those who are at its centre likewise answer to the heart and lungs, and they enjoy the strongest light. The light itself, and consequently the perception of truth, spreads from that centre in all directions towards the circumference, thus reaching all the members of the community and bringing them spiritual life. A demonstration showed that on the removal of those at the centre, who made up the province of the heart and lungs and enjoyed the strongest light, the surrounding people had a shadow cast upon their understandings, and had such a tenuous perception of truth that they complained. But as soon as those at the centre returned, they saw the light and their perception of truth was as before.
This can be compared with heat and light coming from the sun of the world, which gives trees and plants the power to grow, even if they are placed to one side and are under a cloud, so long as the sun is above the horizon. The same is true of the light and heat of heaven coming from the Lord as the sun there. This light is in essence Divine truth, the source of all intelligence and wisdom for angels as well as men. This is why it is said of the Word that it was with God and was God, that it enlightens everyone who comes into the world; and that the light also shines in the darkness (John 1:1, 5, 9). The Word there means the Lord in respect of Divine truth.
