People fear nothingness. However in zen, we are taught to value emptiness as a source of potential and creativity. Think of it as an empty garden or an empty canvas. We have to let go to be empty, and it is in that emptiness where we can start cultivating again.
The inherent superiority of emptiness over form and stillness over activity, as well as their indivisible interdependence, is a salient point in many Asian philosophies.
