107. That this is the case in the universal heaven may be inferred from the similar conditions that prevail in each of the heavenly societies; for every society of heaven is a heaven in a smaller form, and is also like a man. That such is the case may be seen in Heaven and Hell (n. 41-87). In each society of heaven also, those in the center correspond to the heart and lungs, and they possess the greatest light. This light, and the consequent perception of truth, propagates itself from that center toward the successive circuits in every direction, thus to all in the society, and it makes their spiritual life. It has been shown that when those in the center who constituted the province of the heart and lungs and possessed the greatest light, were taken away, those around them came into shadow, and into a perception of truth so scanty as to be almost none; but as soon as the others came back, the light reappeared, and they had perception of truth the same as before.
