This may be compared to the eyes, which are two as organs but one in respect to the sight; also to the ears, which are two as organs but one in respect to hearing; so, too, the arms and the feet are two as members but one in respect to use, the arms one in respect to action, and the feet one in respect to walking. So with the other pairs with man. All these have reference to good and truth, the organ or member on the right to good, and that on the left to truth. It is the same with a husband and wife between whom there is a true marriage love; they are two in respect to their bodies but one in respect to life; consequently in heaven the married pair are not called two angels but one. All this makes clear that through marriage man becomes a form of love, and thus a form of heaven, which is an image and likeness of God. Man is born into a love of evil and falsity, which love is the love of adultery; and this love cannot be turned about and changed into spiritual love, which is an image of God, and still less into celestial love, which is a likeness of God, except by a marriage of good and truth from the Lord, and not fully except by a marriage of two minds and two bodies. From this it is clear why marriages are heavenly and adulteries infernal; for marriage is an image of heaven, and true marriage love is an image of the Lord, while adultery is an image of hell, and love of adultery is an image of the devil. Moreover, marriage love appears in the spiritual world in form like an angel, and love of adultery in form like a devil. Reader, treasure this up within you, and after death, when you are living as a spirit-man, inquire whether this is true, and you will see. (A.E., n. 984.) How profane and thus how much to be detested adulteries are can be seen from the holiness of marriages. All things in the human body, from the head to the sole of the feet, both interior and exterior, correspond to the heavens, and in consequence man is a heaven in its least form, and also angels and spirits are in form perfectly human, for they are forms of heaven. All the members devoted to generation in both sexes, especially the womb, correspond to societies of the third or inmost heaven, and for the reason that true marriage love is derived from the Lord's love for the church, and from the love of good and truth which is the love of the angels of the third heaven; therefore marriage love, which descends therefrom as the love of that heaven, is innocence, which is the very being (esse) of every good in the heavens. And for this reason embryos in the womb are in a state of peace, and when they have been born as infants are in a state of innocence; so, too, is the mother in relation to them.
