‘A monk quoted a verse of Ch’an master Wo-lun:
Wo-lun has a skill,
Cutting off a hundred thoughts.
When mind is not aroused in face of objects,
Enlightenment grows day by day.
When the Master heard this, he said, “This verse does not yet clarify the ground of mind. If you put it into practice, that will add to your bondage.” Accordingly, he taught a verse that said,
Hui-neng has no skill,
Does not cut off a hundred thoughts.
In face of objects, mind is aroused again and again;
How can enlightnment grow?’
(The Platform Sutra of the Sixth Patriarch)
