注維摩詰經 5.216

5.216

肇曰：明攀緣之境也。三界外法無漏無為，其法無相，非是妄想所能攀緣。所能攀緣者，三界而已耳。生曰：三界之法耳，非實理也。

[Seng]zhao says: This clarifies the sphere of grasping. Dharmas beyond the three realms are untainted and unconditioned; those dharmas are signless and are not what false conception can grasp. What can be grasped is merely the three realms. [Dao]sheng says: Merely the dharmas of the three realms, not the true principle.
