Chakra is a Sanskrit word meaning wheel, the chakras are energy vortices allowing energy to pass freely through the subtle bodies.
There are over 300 minor chakras throughout the subtle bodies. Seven of these are referred to as the main chakras, these are the root, sacral, solar plexus, heart, throat, third eye and crown chakras. The 7 main chakras are joined at intervals along the spine on the etheric plane. Their function is to receive white light drawn in from the aura that is broken down into its component colors. They allow the free flow of energy, which promotes good health and vitality. If an energy blockage arises this may cause physical ailments that correspond to the area of the blockage, by working with the chakras a balance of energy can be maintained and the health and well being of the person stabilized.
There are many methods that can be used to aid balance in the chakra system. Meditation, spiritual healing and acupuncture are all excellent methods of keeping your energy centers in balance, but simply eating a healthy diet and taking regular exercise will help too.
Each of the seven main chakras is connected to a corresponding gland or organ in the physical body. A blockage of energy in a chakra my affect the area that the chakra is connected to. As we can see below each chakra is also represented with its own color. You may notice that these colors are the colors of the spectrum, each of progressively higher vibration as we move up the chakra system.
