"No, no," Kisuke says, waving a hand dismissively. "You're fine in that body of yours. You're connected to it by that chain still anyway, so it's dangerous to leave it. What I mean is ... don't take having the power I'm going to pull out of you to mean that you need to always use it. It's not your job as a living human being to go out of your way to control the flow of souls. It can be the job of those that it belongs to. That's not to say I think you should be selfish, far from it. There aren't enough people here that can do anything proper with lingering souls."

He shrugs again, bending for his hat and dusting the top of it off with one palm, eyes drifting away from Dean. "Know when to walk away, before you start becoming a ghost yourself, if you take my meaning. Maybe I'm telling you something you already know, Winchester-san, but people who live in this world and deal in that one are walking a thin line. To be forced to live life as a dead man is still a better sentence than to have only death as a living one."
