376. It is permitted to introduce here, in the way of evidence, a representation of the correspondence of the will and understanding with the heart and lungs which was seen in heaven among the angels. By a wonderful flowing into spiral movements, such as no words can express, the angels formed the likeness of a heart and the likeness of lungs, with all the interior structures therein; and in this they were falling in with the flow of heaven, for heaven from the inflowing of love and wisdom from the Lord strives to come into such forms. They thus represented the conjunction of the heart and lungs, and at the same time the correspondence of these with the love of the will and with the wisdom of the understanding. This correspondence and union they called the heavenly marriage; saying that in the whole body, and in its several members, organs, and viscera, it is the same as in the things belonging to the heart and lungs; also that where the heart and lungs do not act, each in its turn, there can be no motion of life from any voluntary principle, and no sensation of life from any intellectual principle.
