The Sanskrit word chakra means “plexus,” “wheel,” or “vortex.” It refers to a number of centers in the subtle anatomy of the human being, with each center corresponding to a different level of consciousness. Chakras are known by various names, including pranic centers, psychic centers, psycho-energetic centers, and cerebrospinal centers. The yogic tradition mentions different chakra systems, out of which the six-chakra system is the most popular.
