二、約真緣。「常住三昧寂而常照」者，心外無境，魔豈能藏形耶？分真懸見，其事可知。若圓初心唯達實相，恣其變怪寂爾如空。「須備方鏡至不能變本形」等者，《抱朴子》曰「昔張蓋蹋及偶豪成二人，精思於蜀雲臺山石室中。忽有四人，黃絹單衣葛巾往到其前，曰：『勞乎道士辛苦幽隱。』於是二人顧視鏡中，乃鹿也。」《續搜神記》曰「林盧山下有一亭，人每過此宿者或病死。時有郅伯夷者，宿於此，明燭而坐。中夜忽有十餘人來，自共蒲博。伯夷密以鏡照之，乃是群犬。」

Second, on true [nature] and conditioned [arising]. Regarding "the eternal samādhi being quiescent and yet constantly shining": since there are no objects outside the mind, how could a demon conceal its form? With partial truth seeing from afar, this matter is evident. If at the initial mind of the perfect teaching, one only reaches true reality; though [the demon] indulges in transformations and monstrosities, one remains quiescent like space. Regarding "one must prepare a square mirror up to cannot change its original form": the *Baopuzi* states: "Formerly, Zhang Gaipi and Ou Haocheng were meditating in a stone chamber on Mount Yuntai in Shu. Suddenly, four people in unlined yellow silk robes and kudzu headbands came before them, saying: 'How toilsome, Daoists, are your bitter seclusion and practice!' Thereupon the two men looked into a mirror, and they were in fact deer." The *Xu soushen ji* states: "At the foot of Mount Linlu was a pavilion; people passing and lodging there often fell ill or died. At that time, there was Zhi Boyi, who lodged there and sat with a bright candle. In the middle of the night, a dozen people suddenly came, playing gambling games among themselves. Boyi secretly illuminated them with a mirror, and they were a pack of dogs."
