Rub your hands together as if you were warming them up on a chilly day. Once they are nice and warm, with the palms of your hands facing each other, take your hands about 1 inch apart. Feel the warmth, energy and vibration in the space between between your hands. If you look carefully you may even be able to see the vibration.
Once you can feel this, start to move your hands slowly away from each other, still maintaining this feeling. Take them slowly apart, palms still facing, until you could fit a medium sized ball between your hands - like one of those little soft beach balls with the Disney characters on it!
Feel this ball of energy, and rotate your hands as if you were holding this ball between your hands and turning it from side to side. Try pulsing your hands inwards, as if slightly squeezing the ball or compressing the energy between your hands. Have fun with this.
Once you have a strong feeling of this energy, take the ball to any part of your body that could use some extra energy - take it to your neck for a sore throat, or your stomach for some indigestion, etc - any part of your body that feels pain or discomfort. You could also take it to a part of your body that you associate with a particular emotion that is bothering you - to your heart for an intense sadness, or your liver for strong feelings of anger, for instance.
Take the ball of energy and press it into that part of your body and then rub your body with both hands, feeling the energy entering and working it's healing magic.
Try this yourself, and teach it to your kids. It doesn't need to take long - 2 or 3 minutes is fine, and so is ideal for little ones with short attention spans. They love it, and it helps to give them some feeling of control and power over their own bodies - knowing that they can heal themselves and don't need to look externally for a solution every time.
