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.)
