56. Verse 29 And God said, Behold, I give you every plant yielding seed which is upon the face ¹ of the whole earth, and every tree in which there is fruit, the tree producing seed will be for you for food. A celestial man takes delight in none but celestial things, and because these suit his life they are called celestial food. A spiritual man takes delight in spiritual things, and because they suit his life they are called spiritual food. The same applies to a natural man and natural things, and because they suit his life they too are called food, and are chiefly facts. Here, since the subject is the spiritual man, his spiritual food is described by representatives, that is to say, spiritual food is represented by 'the plant yielding seed' and by 'the tree in which there is fruit', which in general are called 'the tree producing seed'. His natural food is described in the next verse.

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.
