“To attain enlightenment, it is not necessary to abandon family life, quit your job, become a vegetarian, practice asceticism, flee to a quiet mountaintop, or enter a ghost cave of dead Zen to entertain your subjective imaginings. If you have been practicing quiet meditation but your mind is still not calm and free when in the midst of activity, this means you haven’t been empowered by your quiet meditation.
“Furthermore, if you have been practicing quietude just to get rid of agitation, then when you are practicing quietude just to get rid of agitation, then when you are in the midst of agitation, the agitation will disturb your mind just as if you had never done any quiet meditation.
“When you are studying Zen, as you meet with people and deal with situations, never allow erroneous thoughts to continue. If an erroneous thought arises, immediately focus your attention and root the thought out. If, however, you just follow the thought unhindered, this will not only make it impossible to have any insight into your own true nature it will also make you a fool.
“Good and bad come from your own mind. However, what do you call your own mind, apart from your actions and thoughts? Where does your mind come from? If you really know where your own mind comes from, boundless obstacles caused by your own actions will be cleared all at once. After seeing that, all sorts of extraordinary possibilities will come to you without your seeking them.”
