From warriors ravens grew red And with their leader a host attacked.
 Taliesin
Monks congregate like dogs in a kennel, From contact with their superiors they acquire knowledge, Is one the course of the wind, is one the water of the sea? Is one the spark of the fire, of unrestrainable tumult? Monks congregate like wolves, From contact with their superiors they acquire knowledge. They know not when the deep night and dawn divide. Nor what is the course of the wind, or who agitates it, In what place it dies away, on what land it roars.
