The body is the tree of enlightenment,
The mind like a clear mirror stand;
Time and gain wipe it diligently,
Don't let it gather dust.

- Shenxiu

Enlightenment is basically not a tree,
And the clear mirror is not a stand.
Fundamentally there is not a single thing -
Where can dust collect.

- Huineng, Sixth Zen Patriarch in China, 638-713
