3.81

[The Master] cited: "Xuansha asked a monk, 'Where have you recently left?' The monk said, 'Ruiyan.' Xuansha said, 'What words does Ruiyan have?' The monk said, 'He constantly calls to the master [of himself], and answers himself, "Yes. Stay awake! In later times, do not be deceived by others."' Xuansha said, 'Though it is just playing with the spirit, it is quite extraordinary. Why did you not stay there for a while?' The monk said, 'Ruiyan has passed away.' Xuansha said, 'If you call him now, will he still respond?' There was no answer." The Master said, "Blue heaven, blue heaven!"
