When you see a speck of dust, it is not that you do not see the world of phenomena. When you realize the world of phenomena, it is not that you do not realize a speck of dust. When buddhas realize the world of phenomena, they do not keep you from realization. Wholesomeness is manifest in the beginning, middle, and end.
