注維摩詰經 3.335

3.335

肇曰：法身無為而無不為，無不為故現身有病、無為故不墮有數。生曰：雖曰無漏，或有為也。有為是起滅法，雖非四大，猶為患也。佛既以無漏為體，又非有為，何病之有哉？為，則有數也。

[Seng]zhao says: "The dharmakāya is unconditioned, yet there is nothing it does not do. Because there is nothing it does not do, it manifests a body with illness; because it is unconditioned, it does not fall into conditioned reckoning." [Dao]sheng says: "Although it is called undefiled, it might be conditioned. The conditioned is the dharma of arising and ceasing; though it is not the four great elements, it still constitutes an affliction. Since the Buddha has the undefiled as his substance and is moreover not conditioned, what illness could there be? If it were conditioned, it would fall into reckoning."
