"Under a rider who has a heart for the animal, the correctly trained horse will work with joy and happiness, while a horse that carries its rider with fear and hesitation accuses him of being unfair and cruel. Riders who espouse the principle that one must intentionally challenge the horse's resistance in order to break it, should be careful that they do not experience the fate of the sorcerer's apprentice who eavesdropped on his master to learn the magic words about the evil spirits which he then was able to call into action but, filled with terror, could not banish."
