48:4.16
The need for the relaxation and diversion of humor is greatest in those orders of ascendant beings who are subjected to sustained stress in their upward struggles. The two extremes of life have little need for humorous diversions. Primitive men have no capacity therefor, and beings of Paradise perfection have no need thereof. The hosts of Havona are naturally a joyous and exhilarating assemblage of supremely happy personalities. On Paradise the quality of worship obviates the necessity for reversion activities. But among those who start their careers far below the goal of Paradise perfection, there is a large place for the ministry of the reversion directors.
