chakra

Chakras are also, in Yoga and many new-age psychic circles, the energy points in the spirit/soul/energy body where different kinds of energy flow through. As one progresses from bottom to top, each chakra delves into theoretically more complex forms of thought and emotion. There are seven, though some consider the eighth to be the aura or something along those lines. There can really be more or less, depending on how complex the mysticism makes it. I've seen three, and I've seen 20+ (usually any beyond 7 include 'lesser' chakras, energy conduits on the body that don't serve a function other than taking in and expelling psychic energy).
