Now, create an artificial wave . . . consciously add a new component . . . choose a single thought . . . and consciously set about making that thought dominant . . . so that a continuous sequence of even waves all coming from one direction overrides all the choppy water, as an ocean wave absorbs all the eddying waters at the shoreline. Now each wave is that same thought over and over again . . . no other thought can capture your attention which remains fixed upon the single thought.
