Muzhou Daoming
Jap., Bokushu Domyo   (alt. sp.--Bokuju)
Muzhou (city in old China)    Dao Bright
born:  780
died:  877   97 years

place:  China
Chan master:  Huangbo (J., Obaku)
Chan disciples:  Yunmen (J., Ummon), ...
aka: Chen Laoren (Old Man Chen, his surname),
"Sandal Chen" (as he made sandals for a living)
Mu Chou (old W.G.)

Osho uses the
Bokuju name many times in his
discourses, refering to a Zen master. This most
likely is actually
"Bokushu", the Japanese
pronunciation for
Muzhou, as no other 'Bokuju' is
to be found in the Zen literature. This alternate
Japanese romanization may derive from early
English translations of Zen writings.
Muzhou is known in the Zen story of slamming
the door on
Yunmen's (his disciple) leg,
breaking it, causing his enlightenment.
stories:

Blue Cliff Record, Case 10, Empty Headed Fool.

One Zen monk, Bokuju, is reported to have
said, "The world is the same, but nothing is the
same because the mind changes. Everything
remains the same, but nothing is the same
because I am not the same..."
