The third Chakra is located straight behind the navel.
When you concentrate,
concentrate on the spot two inches above your navel.
Using your fingers,
press on the point two inches above your navel,
on the point called the Joong-wahn.
Now release the pressure of your fingers.
Concentrate on the point just behind them.
Feel the beating of your pulse.
When you inhale,
breath comes in through the Joong-wahn point.
When you exhale, the breath goes out the same way.
Observe the organs surrounding the Joong-wahn
with your mind’s eye…
The third Chakra connects with the stomach.
It  also controls the liver, gall bladder and pancreas.
