402. (4) Love or the will prepares a home or bridal chamber for its future spouse, which is wisdom or the intellect. Present in the created universe and in each of its constituents is a marriage of goodness and truth, and this for the reason that goodness is a property of love, and truth a property of wisdom, and these two are in the Lord, from whom come all created things. How this marriage is formed in the human being can be seen mirrored in the conjunction of the heart with the lungs, for the heart corresponds to love or good, and the lungs to wisdom or truth, as stated above in nos. 378-381, 382-384. From that conjunction it can be seen how love or the will betroths to itself wisdom or the intellect, and afterward marries it or enters as though into a marriage with it. Love betroths wisdom to itself by preparing a home or bridal chamber for it, and it marries it by joining it to itself through affections and then living wisely with it in that home. [2] The reality of this can be fully described only in spiritual language, because love and wisdom, and consequently the will and intellect, are spiritual. They can indeed be presented in natural language, but only to a hazy perception of them owing to people's not knowing what love is, what wisdom is, and so what affections for good are, and what affections for wisdom, or affections for truth, are. Nevertheless, the nature of the betrothal and marriage of love with wisdom or of the will with the intellect can still be seen by the parallel afforded by their correspondence with the heart and lungs. For the case with the latter is the same as with the former, so much the same that there is no difference whatever, except that one is spiritual and the other natural. From the heart and the lungs, therefore, it is clear that the heart first forms the lungs, and afterward conjoins itself with them. It forms the lungs in the fetus, and conjoins itself with them after birth. This the heart does in its home, called the breast, where the two have their joint abode, separated from the rest of the body's organs by a membranous partition called the diaphragm and by a covering called the pleura. The same is the case with love and wisdom or with the will and intellect.
