213. As for love and wisdom, love is the purpose, wisdom the means, and service the result. Further, service is the composite, vessel, and foundation of wisdom and love, such a composite and such a vessel that every bit of love and every bit of wisdom is actively present in it. It is their total presence. We need to be absolutely clear, though, that in keeping with what was presented in 189-194 above, what are present in service are all the elements of love and wisdom that are of the same kind, harmonious.

6314. As it is with light, so it is with the heat that is vital to a person's existence. In no way at all does that vital heat originate in the heat radiated by the sun in the world; rather, it originates in spiritual heat, which is love and radiates from the Lord. This heat is what angels have. Consequently the amount of vital heat a person has is determined by the amount of love he has. His body however is warmed by worldly heat, as is his sensory awareness within it; yet vital heat flows into that worldly heat and imparts life to it. Differences in the purity and intensity of this heat are akin to variations in the clarity of the light. This vital heat is what one should understand by the holy fires mentioned in the Word, and therefore heavenly loves are meant by those fires. But in a contrary sense that worldly heat is what one should understand by the fires of hell, and therefore hellish loves and the desires that go with them are meant when these fires are mentioned in the Word.
