If you persist in trying to attain what is never attained (It is Tao’s gift),
If you persist in making effort to obtain what effort cannot get,
If you persist in reasoning about what cannot be understood,
You will be destroyed by the very thing you seek.
To know when to stop,
To know when you can get no further by your own action,
This is the right beginning!
- Chuang Tzu, Trans. T.Merton
