大般涅槃經集解 54.59

54.59

案道生曰：從「以何義故」至此，第二問也。既問佛性以種生為義，以若生滅故，云何故復名常樂我淨耶？僧亮曰：第三問所以得稱常等四義也。僧宗曰：通因果問也。寶亮曰：偏問果性。何故獨稱常樂我淨耶？

Daosheng says: From 'For what reason' to here is the second question. Having asked that the buddhadhātu takes producing from seeds as its meaning, and since it is thus subject to arising and cessation, why is it also named permanence, bliss, self, and purity? Sengliang says: The third asks why it can be called by the four meanings of permanence and so forth. Sengzong says: It asks comprehensively about cause and effect. Baoliang says: It specifically asks about the nature of the fruit. Why is it solely called permanence, bliss, self, and purity?
