You should be aloof
and independent — stand alone and go alone.
You should cut off sentiments and detach from perception
and make yourself empty and silent so there is not a single thing
that can be grasped. Cut off the myriad entanglements, and make
yourself free and untrammeled, and reach the stage of great
peace. When this is closely continuous without any leaks,
this is what is called standing like a wall
miles high, lofty and steep.
