注維摩詰經 9.264

9.264

肇曰：不盡有為，故無閡德之累；不住無為，故無獨善之閡。此二無閡門，是菩薩弘道之要路，佛事無方之所由。勸彼令學，示其佛事不思議道，令必審諸佛無若干也。

[Seng]zhao says: Because they do not exhaust the conditioned, they are free from the encumbrance of hindering virtue; because they do not abide in the unconditioned, they are free from the hindrance of solitary goodness. These two unhindered doors are the vital path for bodhisattvas to propagate the Way, and the source from which buddha-works proceed unfailingly. He urges them to learn it, showing them the inconceivable way of buddha-works, so that they will surely discern that the buddhas are not diverse.
