A time will come when it won’t pass.’
The gunslinger made no reply, for he knew this was true. The trap had a ghastly perfection. If someone told you you’d go to hell if you thought about seeing your mother naked (once when the gunslinger was very young he had been told this very thing), you’d eventually do it. And why? Because you did not want to imagine your mother naked. Because you did not want to go to hell. Because, if given a knife and a hand in which to hold it, the mind would eventually eat itself. Not because it wanted to; because it did not want to.
