"I am always hoping that there will be some twins in the marriages which I perform. That would make me happy. You see, love is something that you can leave behind you when you die. It's that powerful. The nagi, the soul, it will roam and travel. If two people loved each other very much they come back again as twins. They had a great love, they're whirling around there, and the Great Spirit has pity and lets them come up again. Those little traveling souls come right back in again - twins, triplets, not only lovers but a brother and sister too who were especially fond of each other could come back like this. One reborn this way could carry a memory going way back. I used to know one, a man named Somebody, who remembered part of his former life over 200 years ago."
