Really, the fundamental, ultimate mystery -- the only thing you need to know to understand the deepest metaphysical secrets -- is this: that for every outside there is an inside and for every inside there is an outside, and although they are different, they go together.

Zen does not confuse spirituality with thinking about God while one is peeling potatoes. Zen spirituality is just to peel the potatoes.

Man suffers only because he takes seriously what the gods made for fun.

...he asked, "Where are you today, right now?"
Eagerly, I started talking about myself. However, I noticed that I was still being sidetracked from getting answers to my questions. Still, I told him about my distant and recent past and about my inexplicable depressions. He listened patiently and intently, as if he had all the time in the world, until I finished several hours later.
"Very well," he said. "But you still have not answered my question about where you are."
"Yes I did, remember? I told you how I got to where I am today: by hard work."
"Where are you?"
"What do you mean, where am I?"
"Where Are you?" he repeated softly.
"I'm here."
"Where is here?"
"In this office, in this gas station!" I was getting impatient with this game.
"Where is this gas station?"
"In Berkeley?"
"Where is Berkeley?"
"In California?"
"Where is California?"
"In the United States?"
"On a landmass, one of the continents in the Western Hemisphere. Socrates, I..."
"Where are the continents?
I sighed. "On the earth. Are we done yet?"
"Where is the earth?"
"In the solar system, third planet from the sun. The sun is a small star in the Milky Way galaxy, all right?"
"Where is the Milky Way?"
"Oh, brother, " I sighed impatiently, rolling my eyes. "In the universe." I sat back and crossed my arms with finality.
"And where," Socrates smiled, "is the universe?"
"The universe is well, there are theories about how it's shaped..."
"That's not what I asked. Where is it?"
"I don't know - how can I answer that?"
"That is the point. You cannot answer it, and you never will. There is no knowing about it. You are ignorant of where the universe is, and thus, where you are. In fact, you have no knowledge of where anything is or of What anything is or how is came to be. Life is a mystery.
"My ignorance is based on this understanding. Your understanding is based on ignorance. This is why I am a humorous fool, and you are a serious jackass.

It's like you took a bottle of ink and you threw it at a wall. Smash! And all that ink spread. And in the middle, it's dense, isn't it? And as it gets out on the edge, the little droplets get finer and finer and make more complicated patterns, see? So in the same way, there was a big bang at the beginning of things and it spread. And you and I, sitting here in this room, as complicated human beings, are way, way out on the fringe of that bang. We are the complicated little patterns on the end of it. Very interesting. But so we define ourselves as being only that. If you think that you are only inside your skin, you define yourself as one very complicated little curlique, way out on the edge of that explosion. Way out in space, and way out in time. Billions of years ago, you were a big bang, but now you're a complicated human being. And then we cut ourselves off, and don't feel that we're still the big bang. But you are. Depends how you define yourself. You are actually--if this is the way things started, if there was a big bang in the beginning-- you're not something that's a result of the big bang. You're not something that is a sort of puppet on the end of the process. You are still the process. You are the big bang, the original force of the universe, coming on as whoever you are. When I meet you, I see not just what you define yourself as--Mr so-and- so, Ms so-and-so, Mrs so-and-so--I see every one of you as the primordial energy of the universe coming on at me in this particular way. I know I'm that, too. But we've learned to define ourselves as separate from it.

The size of the universe depresses many people, but not me, I'm delighted at it
