• For the ordinary man, whose mind is a checkerboard of crisscrossing reflections, opinions, and prejudices, bare attention is virtually impossible; his life is thus centered not in reality itself but in his ideas of it. By focusing the mind wholly on each objects and every action, zazen strips it of extraneous thoughts and allows us to enter into a full rapport with life.
