癸未貞元十九年。東都聖善寺大師凝公示寂。翰林白樂天作八漸偈吊之。其序曰。居易甞求心要於師。師賜教焉。曰觀覺定慧明通濟捨。由是入於耳貫于心有得也。師今云亡。以八字作偈哀悼之（八偈留傳燈錄）。

In the nineteenth year of Zhenyuan, a guiwei year, Great Master Ninggong of Shengshan Monastery in the Eastern Capital showed quiescence. Bai Letian (Bai Juyi) of the Hanlin Academy composed 'Eight Gradual Verses' to mourn him. His preface said, 'Juyi once sought the essentials of mind from the Master. The Master bestowed instruction upon him, saying: "Observation, awakening, concentration, wisdom, clarity, penetration, rescue, renunciation." Thereupon it entered my ears and penetrated my mind, and I had an attainment. Now that the Master has passed away, I have composed verses on these eight characters to mourn him' (the eight verses remain in the Chuandeng lu).
