107. That this is true of heaven as a whole may be concluded from the fact that a like state prevails in every society there; for every society is a heaven on a small scale, and is also in the human form. This may be seen in HEAVEN AND HELL, Nos. 41-87. In every society of heaven those who are in the centre in like manner represent the heart and lungs; and they enjoy the greatest light. This light, with the consequent perception of truth, diffuses itself from centre to circumference in every direction, thus reaching all in the society and giving rise to their spiritual life. It was shown me that when those in the centre, who constitute the province of the heart and lungs and with whom light was greatest, were removed, those round about them experienced obscurity, and their perception of truth became so feeble as to be hardly appreciable. As soon, however, as the others returned, light reappeared and their former perception of truth was restored.
