Aurea Mediocritas

Were you now to practice keeping your minds motionless at all times, whether walking, standing, sitting, or lying; concentrating entirely upon the goal of no thought-creation, no duality, no reliance on others and no attachments; just allowing all things to take their course the whole day long, as though you were too ill to bother; unknown to the world; innocent of any urge to be known or unknown to others; with your minds like blocks of stone that mend no holes - then all the Dharmas would penetrate your understanding through and through.
