8496. 'Bake what you will bake' means preparing good to be joined; 'and boil what you will boil' means preparing truth to be joined. This is clear from the meaning of 'baking', since it was done by means of fire, as preparing good to be joined; and from the meaning of 'boiling', since it was done by means of water, as preparing truth to be joined - 'water' meaning the truth of faith, 2702, 3058, 3424, 4976, 5668, and 'fire' meaning the good of love, 934, 5215, 6314, 6832, 6834, 6849, 7324, 7852. The fact that preparing them to be joined is meant is self-evident, for what was being baked and boiled was being prepared for the following sabbath day, by which a joining together is meant, as shown immediately above. They were forbidden to kindle fire on the sabbath day, Exodus 35:3, so they could not bake or boil anything then. The word 'bake' is used in connection with bread and the minchah, which was made by means of fire, see Isaiah 44:15, 19; 1 Samuel 28:24; Ezekiel 46:20; Leviticus 6:17; while 'boil' is used in connection with flesh, which was cooked in water, Exodus 29:31; Leviticus 6:28; 1 Samuel 2:13, 15.

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.
