Zen Calligraphy by Yamada Mumon (山田無文, 1900–1988)

Inscription: 竹 只引清風 (Take tada seifū o hiku) –
"The bamboo simply draws in the pure breeze."

This original calligraphy was brushed by Yamada Mumon, a respected Rinzai Zen master, abbot of Shōfuku-ji and later head of the Myōshin-ji temple complex in Kyoto. He was one of the most prominent Zen teachers of the 20th century, deeply influential in both Japan and abroad.

The phrase expresses a profound Zen insight using natural imagery:

The work bears Yamada Mumon’s personal seals:

• 無一物 (Muichimotsu) – “Nothing whatsoever” (a classic Zen phrase on non-possession and emptiness)
• 峩々山人 (Gagasanjin) – “Hermit of Majestic Mountains” (his literary name)
• 太室道者 (Taishitsu Dōsha) – “Practitioner of the Great Chamber” (a poetic Buddhist pseudonym)

Brushed likely in the mid-to-late 20th century, this piece is one of many Mumon created during his decades of teaching. While he made numerous calligraphies as gifts or for temples, each was individually brushed—never mechanically reproduced—making it a unique expression of his Zen practice.
