Suizen
Suizen (吹禅) (“blowing Zen”) is a Zen practice consisting of playing the traditional Japanese shakuhachi bamboo flute as a means of attaining self-realization. Suizen is often considered a traditional practice by the Komusō (“monks of emptiness”), the Zen Buddhist monks of the Fuke sect of Japan who flourished during the Edo period, however scholars report suizen is in fact modern, noting no explicit contemporary accounts. The first explicit use of the term occurred in Kyoto in the early 1950s by the first abbot of the newly-established Myōan-ji temple, Yasuda Tenzan. It was then popularized by music historian Kamisangō Yūkō in 1974, in the sleeve notes of a Columbia Records Japan triple-LP set entitled 'Suizen' (KX-7001-03), where the practice is (without substantiation) attributed to the original komusō monks of the 1600s.

Instrumental music is rare in all Buddhist practice where instruments usually accompany ritual chants if they are used at all. With suizen, the playing of the shakuhachi as a spiritual exercise is at the core of the religious practice, making it unique in the world of Buddhism.

The practice of suizen may be understood in the context of both ancient Buddhist and Chinese classics which exerted a profound influence on Japanese music, which used awareness of sound as a medium of enlightenment.

Breath is also of fundamental significance as the standard practice of sitting Zen meditation (zazen) and so there is a natural link between zazen and suizen. The type of breathing technique required varies from school to school within suizen.

The concept of ichi on jo butsu – the attainment of enlightenment through a single note – became an important aspect of the Fuke sect’s ‘blowing Zen’ as it developed in later periods. The sound produced by the instrument, which was taught along strict and traditional lines in the suizen schools, is not considered important. It is the practice of blowing which leads to enlightenment.

In 1823, Hisamatsu Fūyō (1791–1871) published his short treatise on practices which bear a similarity to suizen, Hitori Mondō ("Self-questioning"). Here, he speaks of “going all the way with intellect and then going beyond intellect” on the path to enlightenment. He distinguishes the form (jitsu) of shakuhachi music played for entertainment from the emptiness (kyo) of Zen instrumental practice.

The shakuhachi repertoire derives from the Fuke original solo pieces, the Honkyoku. For suizen practitioners these are traditionally played in the manner of a personal spiritual practice and not as a public performance.

The traditions of Fuke Zen and suizen continue today both in Japan and around the world.

Modern Origins 
While the styles and philosophies of the original Komusō monks may have bore similarities to suizen, scholars have repeatedly noted an absence of direct, contemporary evidence for its practice prior to the 20th century. Shakuhachi historian and musician Torsten Mukuteki Olafsson writes: "Sadly speaking, the history of suizen misinformation began in 1974 with Kamisangō Yūkō's explanatory text for the Nippon Colombia gramophone record set titled Suizen - a misleading narrative that was subsequently adapted/translated to English... and uncritically spread by and among shakuhachi aficionados in the West ever after."
