In Taoist thought and Chinese alchemy, the lower abdomen is known as the 'lower cauldron', and it can only be reached and activated by deep diaphragmatic breathing (what the Taoists call Yang breathing).
The Tan Tien is also a psychic centre of primary importance, and the main centre for the storage and circulation of Chi and Li energies. The harmonious mixture of Chi and Li energies in the lower abdomen is known in Taoist thought as 'the Inner Circle', The same area also acts as the centre of the 'Outer Circle' of the body, which governs the spiritual and psychic channels of the mind and body, It must therefore be looked after, nurtured and protected, for it is of prime importance for the health of your body, mind and spirit, in both their internal and their external activities.
