大般涅槃經集解 54.215

54.215

案僧亮曰：釋言有者，以未來定得故名有，非今有也。僧宗曰：第一重，寄現有業故必招當果。佛性亦爾，云何不須修道耶？

Sengliang comments: In explaining that it 'exists,' it is called existing because it will definitely be attained in the future, not that it exists now. / Sengzong says: In the first layer, using the presence of karma in the present as a metaphor, it will definitely bring about the future fruit. The buddhadhātu is also like this; how could one not need to cultivate the path?
