The sanskrit word "chakra" means "wheel" or "disc" or "wheel of light" referring to energy points or nodes in the "subtle body". The chakras appear as wheel-like vortices of pure energy. They spin at great speed and in a deeply spiritual person they may become spheres of radiant light energy. Each chakra has its own purpose, association and connection, representing different levels of consciousness. Chakras are usually depicted as a Lotus Flower. Each chakra has a different number of petals. This number connects to the frequency it vibrates at. The crown chakra, also called the thousand petaled Lotus, has the highest frequency. The seven chakras are positioned along the spinal column. They play an important role in the spiritual, emotional, intellectual, and physical levels.
