Except if you say it twice you come out with the baby word for shit.” “I don’t know about that,” the gunslinger said. “Here it means duty, or destiny, or, in the vulgate, a place you must go.” Eddie managed to look dismayed, disgusted, and amused all at the same time. “Then say it twice, Roland, because words like that sound like shit to this kid.” The gunslinger shrugged. “I don’t discuss philosophy. I don’t study history. All I know is what’s past is past, and what’s ahead is ahead. The second is ka, and takes care of itself.”
