An investigative intellect has its limitations, namely that whatever it perceives must be illuminated by its own corrupting light, borne of the arrogance to presume that the world is predisposed to be known (by it). The alternative to knowing is believing – faith. It comes when I have the maturity and humility to withdraw the glare of my critical mind, and simply join. This withdrawal and joining is repentance, because in the absence of thinking what do I do but weep tears of contrition? In taiji terms, hollow chest is the repentant heart: immersing in energy.
