376. Here, by way of evidence, it may be permitted to bring forward a representation of the correspondence of the will and understanding with the heart and lungs, seen in heaven among the angels. By a wonderful inflowing into spirals, inexpressible in words, they formed a likeness of the heart and lungs with all the internal structures therein, and in so doing they were following the flow of heaven, for heaven strives to come into forms like these by reason of the influx of love and wisdom from the Lord. In this manner they were representing the union of heart and lungs and at the same time the correspondence of these with the love of the will and the wisdom of the understanding. They called this correspondence and union the heavenly marriage, saying, that it is the same in the whole body and its individual members, organs and viscera as it is in those which belong to the heart and lungs; and that where the heart and lungs do not act and each perform its part, there can be no motion of life from any voluntary principle, and no sensation of life from any intellectual principle.
