Wu Wei has a double meaning: first, letting Life, Mind, act through you by yourself, becoming still, thought-free, and empty of ego--you are then not doing anything, but being done to, being used; second, pursuing truth impersonally. The usual ways seek personal attainment, achievement, salvation. The aspirant thinks or speaks of "my mind" or "my purification" or "my progress"; hence such ways are self-enclosed, egoistic. Whatever repression of ego that there is occurs only on the surface and merely drives it down to hide in the subconscious, whence it will re-emerge later. These methods are Long Path ones, hence are destined to end in futility and despair. The deeper way of Wu Wei is to lose the ego by doing nothing to seek truth or to improve oneself; adopting no practice; following no path. The Short Path turns realization over to Overself so that it is not your concern any longer. This does not mean that you do not care whether you find truth or not, but that whereas ordinary care for it arises out of desire of the ego or anxiety of the ego or egoistic need of comfort, escape, or relief, Short Path care arises out of the stillness of mind, the serenity of faith, and the acceptance of the universe.
