The word chakra is derived from the Sanskrit word meaning wheel. If we were able to see the chakras (as many psychics, in fact, do) we would observe a wheel of energy continuously revolving or rotating. Clairvoyants perceive chakras as colorful wheels or flowers with a hub in the center. The chakras begin at the base of the spine and finish at the top of the head. Though fixed in the central spinal column they are located on both the front and back of the body, and work through it.
Each chakra vibrates or rotates at a different speed. The root or first chakra rotates at the slowest speed, the crown or seventh chakra at the highest speed. Each chakra is stimulated by its own and complimentary color, and a range of gemstones for specific uses. The chakra colors are of the rainbow; red, orange, yellow, green, blue, indigo, and violet. The size and brightness of the wheels vary with individual development, physical condition, energy levels, disease, or stress.
If the chakras are not balanced, or if the energies are blocked, the basic life force will be slowed down. The individual may feel listless, tired, out of sorts, or depressed. Not only will physical bodily functions be affected so diseases may manifest, but the thought processes and the mind may also be affected. A negative attitude, fear, doubt, etc. may preoccupy the individual.
A constant balance between the chakras promotes health and a sense of well being. If the chakras are opened too much, a person could literally short circuit themselves with too much universal energy going through the body. If the chakras are closed, this does not allow for the universal energy to flow through them properly which may also lead to dis-ease.
Most of us react to unpleasant experiences by blocking our feeling and stopping a great deal of our natural energy flow. This affects the maturation and development of the chakras. Whenever a person blocks whatever experience he is having, he in turn blocks his chakras, which eventually become disfigured. When the chakras are functioning normally, each will be open, spinning clockwise to metabolize the particular energies needed from the universal energy field.
As already mentioned any imbalances that exist within any chakra may have profound effects upon either our physical or emotional bodies. We are able to use our quartz crystals and gemstones to re-balance all our chakra centers and once the chakra has been properly balanced then our body will gradually return to normal.
The reason why crystals and gemstones are wonderful and powerful healing tools are because of what science calls its piezoelectric effect. (You can see this effect in the modern quartz watches).
