71. The reason why none can be principled in love truly conjugial but those who receive it from the Lord, that is, who come directly to him, and by derivation from him live the life of the church, is, because this love, considered in its origin and correspondence, is celestial, spiritual, holy, pure, and clean, above every love implanted in the angels of heaven and the men of the church; as was shewn above, n. 64; and these its distinguishing characters and qualities cannot possibly exist, except with those who are conjoined to the Lord, and by him are consociated with the angels of heaven; for these shun extra-conjugial loves, which are conjunctions with others than their own conjugial partner, as they would shun the loss of the soul and the lakes of hell; and in proportion as married partners shun such conjunctions, even as to the libidinous desires of the will and the intentions thence derived, so far love truly conjugial is purified with them, and becomes successively spiritual, first during their abode on earth, and afterwards in heaven. It is not however possible that any love should become perfectly pure either with men or with angels; consequently neither can this love: nevertheless, since the intention of the will is what the Lord principally regards, therefore so far as any one is in this intention, and perseveres in it, so far he is initiated into its purity and sanctity, and successively advances therein. The reason why none can be principled in spiritual conjugial love, but those who are of the above description by virtue of conjunction with the Lord, is, because heaven is in this love; and the natural man, whose conjugial love derives its pleasure only from the flesh, cannot approach to heaven nor to any angel, no, nor to any man principled in this love, it being the foundation of all celestial and spiritual loves; which may be seen above, n. 65-67. That this is the case, has been confirmed to me by experience. I have seen genii in the spiritual world, who were in a state of preparation for hell, approaching to an angel while he was being entertained by his consort; and at a distance, as they approached, they became like furies, and sought out caverns and ditches as asylums, into which they cast themselves. That wicked spirits love what is similar to their affection, however unclean it is, and hold in aversion the spirits of heaven, as what is dissimilar, because it is pure, may be concluded from what was said in the PRELIMINARY MEMORABLE RELATION, n. 10.
