Because crystals store energy (and, when needed, release energy) it is important that the correct energy is stored within the crystal as they tend to absorb all energy, be it negative or positive.
After cleansing it is useful to energize crystals with healing energy so if you’re an energy worker, all it takes is a few minutes of concentrated energy and concentration of sending love and positive energy, and removing all negativity.
With clean, dry hands, hold a crystal between them while concentrating on the feelings you wish the crystal to retain. If you are a Reiki I practitioner you can charge your crystals with Reiki energy by holding them in your hands and activating this energy within you in whatever ways your Reiki Master may have taught you how to do this.
Pyramids generate negative ions. In addition, they are believed to have a generally balancing effect on the electromagnetic field of the body. This effect is enhanced by the particular materials used, such as pure 24K gold and copper.
Pyramids are often used to charge crystals. This is a popular use for pyramids. It is generally believed that quartz crystals are most effective for this use, as they may hold the charge for several weeks. These crystals can then be used for healing purposes or for programming. Pyramid charging, however, is good for any crystal which seems to need it.
