From Sengtzan (Died 606 Ad/Ce) , The Third Patriarch Of Zen Poem by Michael Shepherd

How may we walk all free and undisturbed
through life, as if there were no other way?
So that our human nature finds no break
between our nature, and all nature's play?
The answer lies in thought: for if our mind
holds any thought that some restriction makes
on truth itself, then Truth is thus constrained
in every part; can never show itself.
For hence comes false requirement, then to judge
between all these embordered things in mind -
Which wearies angered mind, like some old grudge;
No freedom then, nor peace, nor truth, to find.

So curb that game divisive mind will play
with anything at all; that is the Way.
