Part 13 · Chapter 112

And the matter is that that path which is in the middle of the hair is not included among the twelve ways, and that path is divided into six hundred and thirteen other paths, as mentioned there. But these twelve ways surround the skull, apart from that path which is precisely in the middle of the skull.
