If you miss the mark even by a strand of hair, 
You are as distant as heaven from earth.  
If the slightest discrimination occurs, 
You will be lost in confusion.  
You could be proud of your understanding; 
Have abundant realization, or acquire 
Outstanding wisdom and attain the way 
By clarifying the mind. Still, if you 
Are wandering about in your head, 
You may miss the vital path of letting your body leap.
