Yamada Shōji has demonstrated that Herrigel's teacher, Awa Kenzō, never practiced Zen or even studied with a Zen master. While
John Stevens has reproduced a photograph of a calligraphy by Awa that reads "The Bow and Zen are One.", Yamada quotes Awa's biographer
Sakurai Yasunosuke, who wrote "While Kenzō used the phrase 'the bow and Zen are one' and used philosophical language of Mahāyāna Buddhism in particular to describe shadō, he did not approve of Zen unconditionally." Rather, Kenzō emphasized establishing his own religion of archery and claimed he was doing missionary work in promoting it. Stevens, in his biography and compilation of Kenzō's writings, dismisses these objections : 'More preposterous is the argument that Kenzo’s understanding of Zen was faulty because, it seems, Kenzo never did formal meditation or was certified by a Zen teacher. This is a gross misunderstanding of what Zen is meant to be.'
Volker Zotz revealed in his book,
Auf den glückseligen Inseln, concerning Buddhism and German culture, that Eugen Herrigel was a strong advocate of the Nazi party. For his involvement with Nazism he was forbidden to teach at the University for three years after 1945. ==References==
