The horse is the symbol of the mind. When the mind is under control it is like a horse broken in, when it cannot be controlled it is like a restive horse, when its rein is not well in hand it is like a wild horse roaming about in the wilderness. Then the horse is the symbol of life, representing its energy, activity, and beauty. The horse, with its strength and activity, is harmless, useful, intelligent, has feeling, and is different to the donkey. The horse is the comrade in war, and is the dignity of great warriors. The unity that is established sometimes between the soul of the rider and the spirit of the horse is most wonderful. The horseshoe is considered lucky in all countries, for it reminds one of the horse and conveys the impression of the horse's vigor, activity, life, and beauty.
