注維摩詰經 5.118

5.118

肇曰：四大本無，病亦不有，而眾生虛假之疾從四大起，故我以虛假之疾應彼疾耳。逆尋其本，彼我無實，而欲觀其形相，何耶？生曰：亦是因之而非實病。

[Seng]zhao says: The four great elements are fundamentally non-existent, and illness likewise does not exist; yet the empty and provisional illnesses of sentient beings arise from the four great elements, and therefore I respond to their illnesses with an empty and provisional illness. Tracing back to their fundamental basis, both other and self lack reality; so why wish to inspect their outward form? [Dao]sheng says: It is also due to this and is not a real illness.
