Pai-chang 's fox
Is the story of a monk who, after denying that an enlightened person falls into cause and effect, was turned into a wild fox for five hundred lifetimes. He appears to Zen Master Baizhang (Wade-Giles: Pai-chang; Japanese: Hyakujō) and demands a "turning word," a phrase intended to prompt one to realization, to be freed from his animal form. After Baizhang tells him not to ignore cause and effect, the monk confirms that he has been released from his wild fox body and asks to be given a monk's funeral rites. Later, when Baizhang's disciple Huangbo (Wade-Giles: Huang-po; Japanese: Ōbaku) asks what would have happened had the monk not denied cause and effect, Baizhang tells Huangbo to come close so he can answer him. Huangbo steps forward and slaps Baizhang, ostensibly in the awareness that Baizhang had intended to strike him. Baizhang laughs approvingly and compares Huangbo to the Indian monk and Zen patriarch Bodhidharma.
