You should all first put an end to all ties, and lay to rest all concerns; ...do not remember, do not recollect, do not engage your thoughts with them. Abandon body and mind, letting them be free. With mind like wood or stone, mouth makes no object of distinction, mind pursues no activity; then the mind becomes like space, wherein the sun of illumination spontaneously appears... In the presence of all objects, mind being neither still nor disturbed, neither concentrated nor scattered, passing through all sound and form without lingering or obstruction, is called a man of the Way. Not setting in motion good, evil, right or wrong; not clinging to a single thing, not rejecting a single thing, is called a man of the great vehicle... Once affirmation and negation, like and dislike, approval and disapproval, all various opinions and feelings come to an end and can't bind, then one is free wherever he may be; this is called a bodhisattva with a newly aroused mind immediately ascending to the stage of Buddhahood.
~ Keizan Jokin (1268-1325)
