Hey Aaron,
Thanks a lot for the tip. I went to the book store (in Tokyo), and found the nagashidate as you told me in the 7th volume.
Also I checked in the 8th book to see the ro version, but it wasn't -as you said-, which must have slipped their minds when they were making the series.
I currently have a Japanese teacher who taught me how to perform it,
but I posted the discussion here, to see if there is anything online on
the temae.
I once went to the Urasenke Chado research centre in Kyoto, where they had some of the Chanoyu quarterly issues for sale, but not the complete issues.
I didn't buy the green book, because I am planning on getting a full series, so I want to see other updated options.
All the English books just scratch the surface of chanoyu, which can be frustrating, especially when you see the amount of Japanese books in comparison.
Thanks again, and have a nice weekend,
Ahmad
