Spirit Perceptions, Sensations and Suffering of Spirits
254. Do spirits get tired and need rest?
“They have no need for physical rest because they do not feel tired in the same manner. They have no bodily organs requiring the restoration of strength, but one can say that a spirit rests because it is not constantly in a state of activity. They do not act in a material way, its action is intellectual, and its rest is moral. There are times that its thoughts are less active and no longer directed at any special object. When this happens, it is in a state of rest that is unlike anything experienced by the body. The sort of fatigue that may be felt by spirits is proportionate to their inferiority, the higher their degree of elevation, the less rest they need.”
