Practice.

If you think you will get something from practicing zazen, already you are involved in impure practice.  You do not say, “This is enlightenment,” or “That is not right practice.” Even in wrong practice, when you realize it and continue, there is right practice.” 

Actually we do not have any particular name for our practice; when we practice zazen we just practice it, and whether we find joy in our practice or not, we just do it.  But if you make your best effort just to continue your practice with your whole mind and body, without gaining ideas, then whatever you do will be true practice.
