What would it be like, he wondered, to really know the Tao? The Tao is that which first lets the light, then the dark. Occasions the interplay of the two primal forces so that there is always renewal. It is that which keeps it all from wearing down. The universe will never be extinguished because just when the darkness seems to have smothered all, to be truly transcendent, the new seeds of light are reborn in the very depths. That is the Way. When the seed falls, it falls into the earth, into the soil. And beneath, out of sight, it comes to life.
