Tai-no-henka to the left and right, from "Budo" 1938
If you haven’t read "Morihei Ueshiba, Budo and Kamae" yet then you’ll probably want to go back and read that article first.
You may also want to read "Morihei Ueshiba, Budo and Kamae – Part 2", which contains a response from John Stevens to the original article.
Now, take a look at the section above, "Tai-no-henka to the left and right", scanned from Morihei Ueshiba O-Sensei’s 1938 technical manual "Budo".
