Do not remain in the dualistic state;
avoid such pursuits carefully.
If there is even a trace
of this and that, of right and wrong,
the Mind-essence will be lost in confusion.
Although all dualities come from the One,
do not be attached even to this One.
When the mind exists undisturbed in the Way,
nothing in the world can offend,
and when a thing can no longer offend,
it ceases to exist in the old way.
~ Zen Master Seng-Ts’an, Hsin Hsin Ming
