梁朝傅大士頌金剛經 1.184

1.184

涅槃含四德　唯我契真常
齊名八自在　獨我最虛長
非色非聲相　心識豈能量
看時不可見　悟理即形彰

Nirvāṇa contains the four virtues; / only the Self accords with the true and eternal. / Simultaneously possessing the eight sovereign masteries, / the Self alone is most vast and supreme. / Not being marks of form or sound, / how could the mind and consciousness measure it? / When looked at, it cannot be seen; / when principle is awakened to, its form is displayed.
