141. Since the subject now under consideration is the turning of angels and spirits to their own loves by reason of these loves, something shall be said also about loves. The whole heaven is divided into societies according to all the differences of loves; in like manner hell, and in like manner the world of spirits. But heaven is divided into societies according to the differences of heavenly loves; hell into societies according to the differences of infernal loves; and the world of spirits, according to the differences of loves both heavenly and infernal. There are two loves which are the heads of all the rest, that is, to which all other loves are referable; the love which is the head of all heavenly loves, or to which they all relate, is love to the Lord; and the love which is the head of all infernal loves, or to which they all relate, is the love of rule springing from the love of self. These two loves are diametrically opposed to each other.
