In this scene Fast Eddie (Paul Newman) is bothered because he was called a born loser. He then describes what the game of pool is like when he’s in a state of flow, optimal focused consciousness…
Fast Eddie: I coulda beat that guy, coulda beat ‘im cold, he never woulda known. But I just hadda show ‘im. Just hadda show those creeps and those punks what the game is like when it’s great, when it’s REALLY great. You know, like anything can be great, anything can be great. I don’t care, BRICKLAYING can be great, if a guy knows. If he knows what he’s doing and why and if he can make it come off. When I’m goin’, I mean, when I’m REALLY goin’ I feel like a… like a jockey must feel. He’s sittin’ on his horse, he’s got all that speed and that power underneath him… he’s comin’ into the stretch, the pressure’s on ‘im, and he KNOWS… just feels… when to let it go and how much. Cause he’s got everything workin’ for ‘im: timing, touch. It’s a great feeling, boy, it’s a real great feeling when you’re right and you KNOW you’re right. It’s like all of a sudden I got oil in my arm. The pool cue’s part of me. You know, it’s uh – pool cue, it’s got nerves in it. It’s a piece of wood, it’s got nerves in it. Feel the roll of those balls, you don’t have to look, you just KNOW. You make shots that nobody’s ever made before. I can play that game the way… NOBODY’S ever played it before.
Sarah Packard: You’re not a loser, Eddie, you’re a winner. Some men never get to feel that way about anything.

Reminds me of the passage about the butcher in Chuang Tzu.
Yes, I think so too.
Perhaps you should credit Mihaly Csikszentmihalyi for the ideas about “flow.”
I’ll add a link to it, thanks.
