As above so below.
How the human body reflects the creation of the universe.
The singularity – the dantien point puts the bodyweight into a movement so we move and breathe from there.
This becomes the duality at the waist, a 3 dimensional spinning, elasticated ball determining the weighted and the unweighted in movement, connecting and harmonising the body.
This then becomes the four manifestations which are the limbs. The singularity and duality sends the power out through the limbs and when connected harmonises left and right and upper and lower limbs.
Which creates the eight hexagrams of the upper and lower in each limb giving them the jointedness and flexibility required to contain and transmit the power through the changes.
