48:4.11

All beings enjoy this sort of reversion except those who are inherent Creators, hence automatic self-rejuvenators, and certain highly specialized types of creatures, such as the power centers and the physical controllers, who are always and eternally thoroughly businesslike in all their reactions. These periodic releases from the tension of functional duty are a regular part of life on all worlds throughout the universe of universes but not on the Isle of Paradise. Beings indigenous to the central abode are incapable of depletion and are not, therefore, subject to re-energizing. And with such beings of eternal Paradise perfection there can be no such reversion to evolutionary experiences.
