I want to write an extended story about the whole thing and offer that to several media along with the video, just like I did previously with another short doc from Japan. So I kinda can't and won't give everything away under the video. However, I try to answer questions or join a discussion when I can. This thread in particular seemed very interesting, whereas other comments elsewhere don't really make me join the discussion.

There's only so much you can tell with a short video on the internet. Everything can only be a glimpse into a 1,300 year old legacy, and into the mentality of three humans behind it.
