Once a person is able to achieve true singlemindedness in his practice and smash apart the old nest... into which he has settled... Wisdom immediately appears... and the all-discerning Fivefold Eye opens wide.
What is this true meditation? It is to make everything: coughing, swallowing, waving the arms, motion, stillness, words, action, the evil and the good, prosperity and shame, gain and loss, right and wrong, into one single koan.
