大般涅槃經集解 18.241

18.241

案僧亮曰：合第二譬也。僧宗曰：修學無我者，合上乃無去耶？不知我真性者，更合第二譬也。不知無我處者，還道偏執，所修空觀，非就善友習學所得，故非善解也。

Sengliang comments: This applies the second metaphor. Sengzong comments: 'Cultivating and studying non-self' applies to the earlier 'has it really gone away?' 'Not knowing the true nature of the self' further applies the second metaphor. 'Not knowing the locus of non-self' refers back to partial clinging: the contemplation of emptiness they cultivated was not attained by studying under good spiritual friends, and therefore was not sound understanding.
