A real world example of balanced encounters

[Doug McCrae]

John Cassian (b. ca. 360) followed Evagrius as the key author on desert monasticism... He declares that demons vary in aggression, power, and persistence, so that weaker demons are allocated to the younger and more inexperienced monks, while hardened desert warriors are beset by the most virulent demons.
