"There's many different traditions, but in practical terms they all exist to give shape and focus to power. I can only truly teach my own tradition, but of course Onmyoudo takes years of study to learn. I think the best I can offer you under the circumstances here is to teach you how to sense and better control the flow of your own power. You already know how to channel it through your own tools of choice, to a certain extent, what I hope to do is give you a better understanding of what it is you're doing." Subaru would have loved to really teach the Onmyoudo tradition, of course, but it simply wasn't possible--there was a focus on ritual and on very detailed knowledge that he just didn't have the tools or time to teach in this place.
