The fighter is to be always single-minded with one object in view: to fight, looking neither backward nor sidewise. To go straight forward in order to crush the enemy is all that is necessary for him.
D.T. SuzukiNot to be bound by rules, but to be creating one's own rules-this is the kind of life which Zen is trying to have us live.
D.T. SuzukiZen purposes to discipline the mind itself, to make it its own master, through an insight into its proper nature. This getting into the real nature of one's own mind or soul is the fundamental object of Zen Buddhism. Zen, therefore, is more than meditation and Dhyana in its ordinary sense. The discipline of Zen consists in opening the mental eye in order to look into the very reason of existence.
