14 Zen Warnings, Mumon 

1. To follow the compass and keep to the rule is to tie oneself 
   without a rope.
2. Doing what you like in every way is heresy and being among 
   the devil's army.
3. To unify and pacify the mind is quietism and false Zen.
4. Subjectivity and forgetting the objective world is just 
   falling into a deep hole.
5. To be absolutely clear about everything and never to 
   allow oneself to be deceived is to wear chains and a 
   cangue.
6. To think well and ill is to be in Heaven-and-Hell.
7. Looking for Buddha or looking for Truth outside of oneself 
   is being confined in two iron mountains.
8. One who thinks he is enlightened by raising thoughts is 
   just playing with ghosts.
9. Sitting blankly in Zen practice is the condition of a dead
   man.

10. Making progress is an intellectual illusion.
11. Retrogression is to go against our religion.
12. Neither to progress nor retrogress is to be merely a dead 
    man breathing.
13. Tell me now, what are you going to do?
14. You must make the utmost effort to accomplish your
    enlightenment in this life, and not to postpone it into 
    eternity, reincarnating throughout the three worlds.
