The Gateless Gate in Chinese / Japanese...

無門關 is the ancient title for “The Gateless Barrier.” This has both direct meaning and is the title of a 13th-century collection of koans, compiled by a Chinese Chan Master known as Wumen in China (known in Japan as Zen Master Mumon).

While this is the original title, you may see this written as 無門関 in Japan, where the last character, 關, was simplified to 関 after 1945.

無門関 is the specifically Japanese title for “The Gateless Barrier.” This has both direct meaning and is the title of a 13th-century collection of koans, compiled by Zen Master Mumon (actually a Chinese Chan Master known as Wumen in China).

The original title is 無門關, but the last Kanji was simplified to 関 in modern Japan.

大道無門 is a Buddhist proverb that means “The Great Way has no entrance,” “The Great Way is gateless,” or “The Great Path lacks a gate.”

This can be translated in many other ways.

This concept was authored within a long sacred text by 無門慧開 (known as Wúmén Huìkāi in Chinese or Mumon Ekai in Japanese). He was a Chinese Chan Master (in Japanese, a Zen Master) who lived between 1183 and 1260 AD. His most famous work was a 48-koan collection titled “The Gateless Barrier” or “The Gateless Gate” (無門關 Wú Mén Guān in Chinese, or 無門関 Mu Mon Kan in Japanese). This calligraphy title is a notable line from this collection.

I like this reference to the source of this proverb: The Gateless Gate 無門關
