Zen is not morality, it is aesthetics. It does not impose a code of morality.

it does not give you any commandments: "do this, don't do that."

Zen is not a philosophy, it is poetry. It does not propose, it simply persuades.

It does not argue, it simply sings its own song.

Zen says: be empty. Look without any idea. Look into the nature of things but with no idea, with no prejudice, with no presupposition.
