Chakra is a Sanskrit term that means "wheel of light." Each chakra spins, creating an electromagnetic radiation energy field that surrounds our physical body that is known as the Aura. The chakras are often called lotuses, each petal representing certain constituent energies.
A chakra is always "open," since it is the union of spirit and matter manifested as consciousness. The soul as consciousness pervades and holds its bodies of manifestation together as a cohesive, functional unit through certain focal points. In the Indian tradition, these points or centers of force are called Chakras.
