Ikkyu Sojun was a scandal-ridden Japanese Zen
master. He was quite the erotic-minded monk and was highly influential
in many spheres of art. Sam Hamill wrote this about him:
"...(He) was renowned his teaching and
for his frankly erotic poems and revolutionary shakuhachi music.
Headmaster at japan's huge Buddhist training centre, Daitokuji,
in Kyoto, he resigned after nine days, denouncing the monks for
hypocrisy and inviting them to argue their differences "in
the whorehouses and sake parlours" where he could be found.
At seventy, he scandalized the Buddhist community by moving his
lover into his quarters in the templeHis sphere of influence included
the tea ceremony, Noh drama, ink painting, calligraphy, and poetry,
and he founded what became known as the "Red Thread"
(or erotic) school of Zen.
