Chakra is derived from Sanskrit word meaning Wheel.
Observed as wheels of energy continuously rotating at different speeds, Root being slowest, Crown being fastest. They are located on both the front and back of the body, and work through it, beginning at the base of the spine and finishing at the top of the head. The size and brightness of chakras vary with individual development, physical condition, energy levels, disease, or stress.
Each chakra is stimulated by its own color, and gemstones. If energies are unbalanced/blocked, the basic life force is slowed, and individual may feel listless, tired, out of sorts, or depressed. Physical and mental functions may be affected, causing negative attitude, fear, doubt etc.
Balancing chakras promotes health and a sense of well being. If they are too open, a person could “short circuit” themselves with too much universal energy going through the body. If closed, the universal energy can’t flow properly.
