Yellow fills one with inspiration, and red gives one the energy to act upon that feeling. Surround yourself with the colors that help keep you feeling positive and well. By using the specially energized quartz crystal that is included in the kit one can overcome stress, heal minor ailments, and feel more optimistic. Geller suggests that you grasp the crystal in your hand, then hold it up to the light and experience the glorious colors that emit from its different surfaces.
Different crystals promote specific changes in the body.
For example, amethyst has properties that help to cleanse the blood and strengthen the immune system. In dowsing, a physical object, such as two crossed metal rods or an L-shaped metal wire, is used to indicate the presence of a desired object. This technique has been used to locate valuable resources in the earth such as oil and gold. Many people are natural dowsers, but have yet to recognize their skill. Dowsing can be seen as the application of one's sixth sense or psychic ability.
