Hi Bob,
It is a contrivance to attempt to unify "our experiences in a manner consistent with a harmonious existence". Harmony does not consist of "a desire to be harmonious" and then working towards it. Harmony as a principle occurs naturally, of itself, when we “get out of the way” of Tao and “allow it to occur”. Harmony naturally occurs because Tao seeks balance, or IS balance, or maintains balance as an inherent principle of Te.
Once we contrive to create or acquire Harmony we pursue an arbitrarily determined definition. We impose our own idea of what we think Harmony “should” be onto Tao. Having said that, the concept of Balance/Harmony is illustrated by Yin-Yang and observed by direct experience to reflect a rhythmic alternation between two contrasting principles. It is not a still point or fixed condition. It involves both conflict and no-conflict. Balance is maintained when the contrasting principles alternate between their extremes. There is no still point between the two.
Error occurs when we try to project our desire to avoid the unpleasantness of conflict onto Tao by clinging to the desire for a constant condition of no-conflict. By preferring one over the other we actually participate in contriving a condition that will result in a return to the contrasting/opposing principle. The more we cling to one of the contrasting principles the more likely the return will involve a catastrophic/abrupt return.
