401. (iii) Love or the will can do nothing through its human form except by marriage with wisdom or the understanding. This also is clear from the correspondence of the heart with the will. The embryo-man lives by the heart, but not by the lungs; for at that time blood does not flow from the heart into the lungs and enable him to breathe, but through an aperture into the left ventricle of the heart; for which reason the embryo during that time cannot move any part of the body, for it lies bunched up, nor can it feel anything, for the sensory organs are closed. It is the same with love or the will, from which the embryo is all the while living, but in obscurity, without feeling and movement. But as soon as ever the lungs are opened, which takes place after birth, he begins at once to feel and to move, and likewise to will and to think. From these things it can be established that love or the will can do nothing through its human form except by marriage with wisdom or the understanding.
