426. (xxi) Spiritual and celestial love is love towards the neighbour and to the Lord, and natural and sensual love is love of the world and of self By love towards the neighbour is meant the love of uses, and by love to the Lord is meant the love of doing uses, as has been shown before. The reason that these loves are spiritual and celestial is that the love of uses and doing them from love for them is distinct from man's proprium; for he who loves uses spiritually, regards not himself but others outside self, for whose good he is concerned. The loves of self and of the world are opposed to these loves, for they have no regard to uses for the sake of others, but only for the sake of self; and those who perform uses in this way invert the Divine order, and put themselves in the Lord's place, and the world in place of heaven. Thus it comes about that they look backwards, away from the Lord and from heaven, and to look backwards is to look towards hell; but more concerning these loves may be seen above (n. 424). But man does not feel and perceive the love of performing uses for the sakes of uses, as he does feel and perceive a love of performing uses for the sake of self; hence also he does not know, when he does them, whether he is doing them for the sake of uses or for the sake of self. But he may know that in the degree he shuns evils, he is performing uses for the sake of uses; for so far as he shuns them, he does them not from himself, but from the Lord. For evil and good are opposites, and for this reason one comes into good to the extent that one comes out of evil. No one can be in evil and in good at the same time, because no one can serve two masters at the same time. These things are said so that it may be known that, although man does not perceive by sense whether the uses performed are for the sake of use or for the sake of self, that is, whether the uses are spiritual or merely natural, he may yet know it by this, whether or not he considers evils to be sins. If he regards them as sins, and if, on that account, he refrains from doing them, then the uses he performs are spiritual; and when, from a feeling of aversion, he shuns sins, he also begins to have a sensible perception of the love of uses for the sake of uses, and this from a spiritual delight in them.
