From the beginning it’s best to do zazen in the midst of strife and confusion. A samurai, in particular, must be able to do zazen while uttering his battle cry. Guns are firing, lances are flying, and amidst the confusion , you send up a battle cry. It’s here that you can clearly make good use of your practice. What use can there be for a zazen requiring a quiet place? However appealing Buddhist teachings may be, the samurai should throw away anything he can’t use when the moment for his battle cry arrives.
