Try moving your attention down to your center and see how it feels. Then let it float back up. Consider which place feels more secure and quiet to you. Centered is best place to be when working with an animal. When your spirit resides in your center your horse can go around you and not visa versa.
Horses always tell the truth.
Sadly, that truth is sometimes hard to hear. Remember, they are innocents. If you have a fight with your horse, always apologize afterwards. They really do understand. Just be there.
