49. All the societies of heaven have communication with one another, but not by open intercourse, for few go out of their own society into another. This is because going out of their own society is like going away from themselves or from their own life and passing into another life which is less congenial. Yet all communicate by an extension of the sphere which goes forth from the life of each. This sphere of the life is the sphere of the affections of love and faith. This sphere extends itself far and wide into the societies around, extending further and wider in proportion as the affections are more interior and more perfect.# In the measure of that extension, the angels have intelligence and wisdom. Those who are in the inmost heaven, and in the middle of it, have extension into the whole heaven; thus there is communication of all in heaven with each one and of each one with all.## This extension, however, will be considered more fully below where the heavenly form [is treated of] in accord with which the angelic societies are arranged; also the wisdom and intelligence of angels will be treated of, for in accordance with that form all extension of affections and thoughts proceeds. # A spiritual sphere, which is a sphere of life, flows out from every man, spirit, and angel, and encompasses them (n. 4464, 5179, 7454, 8630). It flows forth from the life of their affection and thought (n. 2489, 4464, 6206). These spheres extend themselves far into angelic societies in accordance with the quality and quantity of good (n. 6598-6612, 8063, 8794, 8797). ## In the heavens there is a communication of all goods because heavenly love shares with another all that is its own (n. 549, 550, 1390, 1391, 1399, 10130, 10723).
