Zen 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.

The ego-shell in which we live is the hardest thing to outgrow.

If you have attained something, this is the surest proof that you have gone astray. Therefore, not to have is to have, silence is thunder, ignorance is enlightenment.

Zen wants us to acquire an entirely new point of view whereby to look into the mysteries of life and the secrets of nature. This is because Zen has come to the definite conclusion that the ordinary logical process of reasoning is powerless to give final satisfaction to our deepest spiritual needs.

Who would then deny that when I am sipping tea in my tearoom I am swallowing the whole universe with it and that this very moment of my lifting the bowl to my lips is eternity itself transcending time and space?

The truth of Zen is the truth of life, and life means to live, to move, to act, not merely to reflect.

The claim of the Zen followers that they are transmitting the essence of Buddhism is based on their belief that Zen takes hold of the enlivening spirit of the Buddha, stripped of all its historical and doctrinal garments.
