“Faith keeps you going, but doubt keeps you from going off the deep end.”

The thinking brain influences the body’s responses and it makes a neat little loop.

I mean, I can do that all day long. I can tell you the Vulcan’s are not actually devoid of emotion. That they work hard to suppress their emotions. And of course, there actually are no real Vulcan’s, though I know the ins and outs of them as fictional characters.

What attracted me to Zen was my first teacher, Tim McCarthy. He was extremely genuine. It wasn’t even really a Zen thing, that sort of came along later.

Zen practice is about not getting high on anything and in so doing getting high on absolutely everything. We then find that everything we encounter – bliss or nonbliss – possesses a tremendous depth and beauty that we usually miss.

Do what you do as well as you possibly can. That’s Buddhist morality.

Much of the hatred and fear of sexuality found in religions stems from the idea that sex is a thing of the body and that the body must be denied so that the spirit may be elevated. In Buddhism there is no notion that the body is made of inferior matter while the spirit flies free within.

Leaving home’ to me means adopting the attitude that the pursuit of the truth is more vital than the pursuit of what society – your home – tells you is important.

I was very attracted to the way that Zen did not go into the imagination land. And now I’ve forgotten what your first question was and how we were going to tie this together.

My principal sin is doubt. I doubt everything, and am in doubt most of the time.

Gravity is not a version of the truth. It is the truth. Anyone who doubts it is invited to jump out a tenth-storey window.

A doubtful friend is worse than a certain enemy. Let a man be one thing or the other, and we then know how to meet him.

Today is today, and yesterday is gone. There is no doubt.

Any truth is better than indefinite doubt.

There’s no doubt. Its certain that ill be 100 percent

How prone to doubt, how cautious are the wise!

I talk to God but the sky is empty.
