大般涅槃經集解 2.43

2.43

案僧宗曰：如來道被大千、德蔭三界，今入涅槃，世間空也。福盡者，福以感聖；聖既不應，所以知盡也。不善增長者，福既盡矣，惡所以增。

Sengzong states: The Tathāgata's path covers the great chiliocosm, and his virtue shelters the three realms; now that he enters nirvāṇa, the world is empty. That "blessings are exhausted" means that blessings invoke the sage; since the sage no longer responds, they know [blessings] are exhausted. That "unwholesome things increase" means that, blessings having been exhausted, evil therefore grows.
