Definition of Chakra
The word chakra literally means 'wheel' or 'circle', but in the yogic context it is 'vortex' or 'whirlpool'. The chakras are vortices of pranic energy at specific areas in the body which control the circulation of prana permeating the entire human structure. Each chakra relate to specific areas of the brain, and in most people these psychic centres are inactive. Concentration on the chakras while performing yogic practices stimulates the flow of energy through the chakras and helps to Activate them. This in turn awakens the inactive areas in the brain and the corresponding faculties in the psychic and mental hoodies, allowing one to experience planes of consciousness which are normally inaccessible. The petals of the lotus, inscribed with the bija mantras or seed sounds of the Sanskrit alphabet, represents the different manifestations of psychic energy connected with the Chakras
