3.12

The questioner asks: "If it is said that when causes are exhausted, fruits are exhausted, then when the arhat's path of remedy exhausts the causes of the three realms, shouldn't his recompense body immediately perish?" The commentator explains: "This recompense body is exhausted naturally by the residual momentum of the cause. Just as when a stick is used to turn a wheel, suppose the stick is immediately destroyed, the wheel still turns; when the arhat's causes in the three realms are exhausted, at that time the residual momentum of the recompense body is like the wheel."
