大般涅槃經集解 24.24

24.24

案僧亮曰：唯佛乃得，故非先有也。若非先有，則二難俱釋也。名為有者，有為不善也。三事無為，名為善有也。

Sengliang comments: Because only the Buddha attains it, it is not pre-existent. If it is not pre-existent, then both objections are resolved. Being termed "existence" refers to the conditioned being unwholesome. The three matters being unconditioned is termed "wholesome existence."
