大般涅槃經集解 46.1

46.1

琉璃光與佛論生不生義　辨四相常無常義　出往生不動國義　辯涅槃本有舉闇中井及七寶等譬　顯五種因義謂生因和合因住因增長因遠因辨六度有得名波羅蜜有不得義

Vaiḍūryaprabha discusses with the Buddha the meaning of arising and non-arising; distinguishes the meaning of the permanence and impermanence of the four characteristics; sets forth the meaning of being reborn in the Land of Immobility; distinguishes that nirvāṇa is fundamentally existent, citing analogies of the well in darkness, the seven treasures, and so forth; clarifies the meaning of the five kinds of causes, namely: generative cause, harmonious union cause, staying cause, increase cause, and distant cause; distinguishes whether the six pāramitās obtain the name of pāramitā or do not obtain it.
