All of the body’s joints turn in harmonious efficient sequence.
A deeply wound coil anchored by the foot in the earth is twisted tightly and unwound guiding the ebb and flow of core and limb actions.
When the body is sufficiently neutral (“relaxed”) it serves as a fluid structure for the demands of Yin & Yang flux initiated by a quieted mind.
When the body is perceived by the mind as fluid,
such that it can illustrate Jin like Chinese calligraphy
water-brushed, evaporating under the sun,
QI will be the ruler.
Taijiquan gongfu, martial art flows from this source,
so we say, Yin is the mother of Yang.
