"The principles of Reiki might apply to that ... if I can pluck out his negative energy, and flick it away, it might just drift into the magic of the palace or his ritual room and dissipate away. It might be slow work, it might take time, but it could even be a way to close his mind plains for good, if we can get the darknesses out that way."
