I use that silver wand as a "balancing" tool in order to intensify my energy work.
Each of the 7 gemstones (garnet, topaz, citrine, emerald, aquamarine, lapis lazuli and amethyst) on the wand has its own power and is related to the chakras.
Before performing a healing, I like to clear the patient's aura, balance his/her positive and negative ions (that are usually disturbed by the electrical devices around us), and unify the energy fields around the body.
I might also dissolve a mild pain or stimulate a chakra, if needed.
Be ready to be involved in the healing process : talk, focus, be fully aware, release your emotions, it will work even better...
