602. It is important to note, however, that our intellect can rise up almost into the light that the angels of heaven have, but if our will does not rise along with it, we are still the old self, not the new self. (I have already shown how the intellect lifts the will up with itself, higher and higher.) For this reason, regeneration is primarily a matter of the will, and only secondarily a matter of the intellect. The intellect in us is like light in the world, and our will is like the heat here. Without heat, light brings nothing to life and makes nothing grow; as we know, light has to act in partnership with heat. The intellect that is in the lower part of the mind is actually in the light of this world; the intellect that is in the higher part of the mind is in the light of heaven. Therefore if our will is not lifted up from the lower region into the higher region to join the intellect, it remains at the level of the world. Then our intellect flies up and down, up and down. Every night, though, it flies down and sleeps with our will below, and the two make love like a married man and a whore and bring forth two-headed offspring.

Again, it is clear that if we do not have a new will and a new intellect, we have not been regenerated.
