An erotic element is, however, definitely present in Hakuin's Zen art. Certain of his monumental ichi calligraphies have the appearance of huge phalluses, and there is a sketch of a pillar phallus, a common sight in rural Japan, with this inscription: "Even when the wind blows this doesn't move!".
Hakuin did many paintings of bonseki, a miniature landscape in a tray. The painting served as both a clever satire on misbehaving monks and as a love charm. Ostensibly, the inscription on the painting says,
Mr. Bon,
Are you going to worship
At Ishiyama Temple?
"Bon", however, is a homonym for "monk" in Japanese; near Ishiyama Temple there was a famous red-light district that was really the main attraction. Thus the inscription also means:
Mr. Monk,
Are you going to Ishiyama Temple
To get laid?
