Pirsig was attending the Minnesota Zen Center at the time of writing the book. He has stated that, despite its title, the book "should in no way be associated with that great body of factual information relating to orthodox Zen Buddhist practice". Though it may not deal with orthodox Zen Buddhist practice, Pirsig's book in fact deals with many of the more subtle facets of Zen living and Zen mentality without drawing attention to any religion or religious organization. A number of contemporary authors have explored the relationship between Zen and a number of other disciplines, including parenting, teaching, and leadership. This typically involves the use of Zen stories to explain leadership strategies. In Europe, the Expressionist and Dada movements in art tend to have much in common thematically with the study of kōans and actual Zen. The early French surrealist René Daumal translated D.T. Suzuki as well as Sanskrit Buddhist texts. Over the last fifty years mainstream forms of Zen, led by teachers who trained in East Asia and their successors, have begun to take root in the West. In North America, the Zen lineages derived from the Sanbo Kyodan school are the most numerous. The Sanbo Kyodan is a Japan-based reformist Zen group, founded in 1954 by Yasutani Hakuun, which has had a significant influence on Zen in the West. Sanbo Kyodan Zen is based primarily on the Soto tradition, but also incorporates Rinzai-style kōan practice. Yasutani's approach to Zen first became prominent in the English-speaking world through Philip Kapleau's book "The Three Pillars of Zen" (1965), which was one of the first books to introduce Western audiences to Zen as a practice rather than simply a philosophy. Among the Zen groups in North America, Hawaii, Europe, and New Zealand which derive from Sanbo Kyodan are those associated with Kapleau, Robert Aitken, and John Tarrant. The most widespread are the lineages founded by Hakuyu Taizan Maezumi and the White Plum Asanga. Maezumi's successors include Susan Myoyu Andersen, John Daido Loori, Chozen Bays, Tetsugen Bernard Glassman, Nicolee Jikyo McMahon, Joan Hogetsu Hoeberichts, and Charlotte Joko Beck. Soto has gained prominence via Shunryu Suzuki, who established the San Francisco Zen Center. In 1967 the Center established Tassajara, the first Zen Monastery in America, in the mountains near Big Sur.
