If you understand real practice, then archery or other activities can be zen.

 “If you understand real practice, then archery or other activities can be zen. If you don't understand how to practice archery in its true sense, then even though you practice very hard, what you acquire is just technique. It won't help you through and through. Perhaps you can hit the mark without trying, but without a bow and arrow you cannot do anything. If you understand the point of practice, then even without a bow and arrow the archery will help you. How you get that kind of power or ability is only through right practice.”
― Shunryu Suzuki, Not Always So: Practicing the True Spirit of Zen
