2146. As the day was growing hot. That this signifies from love, is evident from the signification of “heat,” as being in the internal sense love; and since heat belongs either to the day or to the year, love is represented either by the heat of the day or by the heat of the year, according to what is related in the historicals. That “heat” signifies love may be seen from the fact that love is called spiritual heat, and that growing warm is predicated of all affection, even in common speech; and further from the fact that love and its affections, in man’s interiors, as also in his exteriors, and even in his very corporeals, make themselves manifest under the guise of heat; in fact heat has no other origin in connection with man when it flows forth from his interiors. Such however as is the love, such is the heat. Celestial love and spiritual love are what give genuine heat. All other heat, namely, that which is from the loves of self and of the world, and also from other filthy loves, is unclean, and in the other life sinks into what is excrementitious (see n. 1773). Be it known moreover that holiness is never predicated except of love and charity; not of faith except insofar as love and charity are in the truths of faith. Except from this the truths of faith are not holy. (See what was said before, n. 2049)

1773. Spirits who had found delight and joy in the Word of the Lord during their life in the body, have in the other life a kind of joyous heavenly warmth which it has also been permitted me to feel. The warmth of those who had some measure of this delight was communicated to me. It was like a vernal heat, beginning in the region of the lips, and diffusing itself about the cheeks, and thence as far as the ears, ascending also to the eyes, and descending toward the middle region of the breast.

[2] The warmth of those who had been still more affected by delight in the Word of the Lord, and by the interior things of it which the Lord Himself had taught, was also communicated to me; beginning at the breast it ascended thence toward the chin, and descended toward the loins. The warmth of those who had been even more delighted and affected, was still more interiorly joyous and vernal, extending indeed from the loins upward toward the breast, and thence through the left arm to the hands. I was instructed by the angels that this is really the case, and that the approach of those spirits brings such warmths, although they themselves do not feel them, because they are in them, just as infants, children, and youths are not commonly sensible of their own warmth which they have in greater measure than adults and old people, because they are in it.

[3] I was also made sensible of the warmth of some, who had indeed been delighted with the Word, but had not been solicitous about the understanding of it; their warmth was felt in the right arm only. As regards the warmth: evil spirits also can by their artifices produce a warmth which counterfeits delight, and can communicate it to others; but it is only an external warmth, without an origin from internals. Such warmth is that which putrefies and converts food into excrement, like the heat of adulterers, and that of those who have been immersed in filthy pleasures.
