Major centers of both electromagnetic activity and vital energy are recognized in indigenous cultures the world over. 

In the Huna tradition of Hawaii, they are called AUW centers; and in the Cabala, they are the TREE OF LIFE centers. 

In the Taoist Chinese tradition the term is DANTIEN, and in Yogic theory they are called the CHAKRAS.

–William Collins, Subtle Energy

The word chakra means disk, vortex, or wheel. The meridians are the transport system, the chakras are the energy

 stations. The chakras reveal how your history plays into current systems. Every emotionally charged event you have

 experienced is imprinted and recorded in your chakra energy. Memory is energetically coded in your 

chakras just as it is chemically coded in your neurons. Electrical oscillations in the skin above the chakras are in 

the frequency of 100-1600 cycles per second, as contrasted with 0-100 in the brain, 225 in the muscles, and 

250 in the heart.* Your physical and psychological evolution, as well as your spiritual journey, are reflected in your chakras.

Your chakras pull and send energy in/out from your environment. They are spinning clockwise and counter clockwise and 

distributing and sending energy to and from  your body. Light and color move through these chakra centers. 

Since colors are vibrations of energy, each chakra has a vibrational relationship with a particular color.
