Found this really fun book at the used book shop this afternoon
It has 97 very beautiful water color sketches. All of which portray Zen monk Giei Sato's days as an Unsui at Tofukuji monastery(Rinzai-shu).
I later found this YouTube video by Tom Davenport on his personal account of a 7 day Sesshin. In the video Tom uses intercut images and stories from this book. Enjoy.....

Just to note. This video, like the book, is Rinzai-shu.
