Great teaching from Allen Watts, his approach is something to admire.

I want to make one thing absolutely clear.
I am not a Zen Buddhist, I am not advocating Zen Buddhism, I am not trying to convert anyone to it.
I have nothing to sell. I'm an entertainer.

That is to say, in the same sense, that when you go to a concert and you listen to someone play Mozart, he has nothing to sell except the sound of the music.

He doesn’t want to convert you to anything.
He doesn’t want you to join an organization in favor of Mozart's music as opposed to, say, Beethoven's.
And I approach you in the same spirit as a musician with his piano or a violinist with his violin.
I just want you to enjoy a point of view that I enjoy.
