I was thinking about this specific Taiji-term this morning and i spontaneously
linked it to the Bagua.
Untrained people suffer from being double-heavy, which is kind of similar to the state
of “Later Heaven”, where Water and Fire stand in the cardinal axis and “fight” with
each other. Their “Taiji” produces just yin and yin or yang and yang.
Through the training our Taiji should produce yin and yang. Applied to
double-heavy, it would transform into single “heavy” ( yin) and single “light” ( yang).
This would conform to the “Earlier Heaven” where, through balance of water and
fire, heaven (light) and earth (heavy) take their places in the cardinal axis.
