The Wineglass exercise
With your fingers around the stems, walk around with two full (right to the top!) wine glasses. Notice how much easier it is not to spill the wine when you are grounded, centered, and soft with your fingers, than when you tighten and hold the glass stems with tense hands. Practice finding a more grounded, centered self that filters out to soft hands. Note: I recommend doing this in a room with tile floor or outside, where spillage isn’t a concern. Bonus: Go ahead and have a drink when you’re done. (And repeat the exercise as often as needed!)
Ball in the Bowl
Take a large mixing bowl and place any small ball (a tennis ball, for example) in it. Walk around holding the bowl loosely with your arms relaxed, your thumbs just under the outside of the rim, and two or three fingers underneath. Experiment with what you need to do to keep the ball “quiet” in the bowl (ie, not rolling around) as you walk. You will quickly discover that you must not try too hard, hold your breath, or keep a tight hold on the bowl with your hands. If you try to keep the bowl still by tightening your hands, the ball will roll around rapidly. Instead, balance your pelvis by softening your hip joints and dropping your sacrum. Ground yourself, use soft eyes, breathe easily, center yourself, and lengthen your spine up and down. You will discover that your hands become very sensitive in the way they carry the bowl, and the ball will be surprisingly quiet inside it. This is the quality of hands that you want when communicating with your horse through the reins.
