大般涅槃經義記 3.166

3.166

第四簡偽異真之中，「若人破戒」明其無行，「為利養故說佛無常」明其無解，「如是之人不應依止，此義決了故名定義」，此明向前所依人者依於如來，不依如是破戒之人。

In the fourth section, which distinguishes the false from the genuine: "If a person breaks the precepts" explains that they lack practice; "and for the sake of material gain preaches that the Buddha is impermanent" explains that they lack understanding; "such a person should not be relied upon; this meaning is decisively understood and is therefore called definitive meaning" explains that the person to be relied upon mentioned before means relying on the Tathāgata, not relying on such precept-breaking persons.
