When a man loves he grows warm, and when he thinks from wisdom he sees things as it were in light; and from this it is evident that the first proceeding of love is heat, and the first proceeding of wisdom is light. That they are also correspondences is evident; for heat does not exist in love itself, but from love in the will and hence in the body; and light does not exist in wisdom, but in the thought of the understanding, and hence in speech. Wherefore love and wisdom are the essence and life of heat and light. Heat and light are what proceed, and because they are what proceed, they are also correspondences.
