維摩經玄疏 1.39

二、名字即者，如《大涅槃》云「外人舊醫，虛妄計涅槃常、樂、我、淨，如蟲食木，偶得成字，是蟲不知是字非字；有智之人，終不說言：『是蟲解字』」。今末世學問、坐禪之人，聞此大乘方等經說「淫、怒、癡性，即是解脫，即大涅槃，不可復滅」，不究深義，執此即名，謂真解脫，是則同彼舊醫蟲道之過，此是名字即也。

Second, as for identity in verbal designation: as the Mahāparinirvāṇa [Sūtra] says, 'Outsiders and former physicians falsely reckon the permanence, bliss, self, and purity of nirvāṇa. It is like an insect eating wood that happens to form characters: the insect does not know whether it is a character or not a character. A wise person will never say, "This insect understands characters."' Now, in the final age, those who study and sit in meditation, hearing this Mahāyāna Vaipulya sūtra say, 'The nature of lust, anger, and delusion is liberation, is great nirvāṇa, and cannot be extinguished again,' do not investigate the deep meaning, cling to this nominal identity, and claim it to be true liberation. This is the same fault as those former physicians and the insect's carving. This is identity in verbal designation.
