134. The heat of heaven, like the light of heaven, is everywhere different. It is different in the celestial kingdom from what it is in the spiritual kingdom, and it is different in each society therein. It differs both in degree and in quality. It is more intense and more pure in the Lord's celestial kingdom, because the angels there receive more of Divine good; and it is less intense and pure in His spiritual kingdom, because the angels there receive more of Divine truth. Also in each society the heat differs in accordance with reception. There is heat in the hells, but it is unclean heat. ¹ The heat in heaven is what is meant by holy and heavenly fire, and the heat of hell by profane and infernal fire. Both mean love - heavenly fire meaning love to the Lord and love to the neighbor and every affection of those loves, and infernal fire meaning love of self and love of the world and every lust of those loves. That love is heat from a spiritual source is shown from one's growing warm with love; for in accordance with the strength and nature of his love a man is inflamed and grows warm; and the heat of his love is made manifest when it is opposed. From this also it is customary to speak of being inflamed, growing hot, burning, boiling, being on fire, both in regard to the affections of the love of good and the lusts of the love of evil.
