大般涅槃經義記 8.247

8.247

下佛答之，先對初問辯見相，「如來之身有二種」下釋去後難明其可見。前中，先明見如來相。「佛身二種」略標所見，「常與無常」列其二名，下約此二彰其見相。其「無常者，為度眾生方便示現應化之身，可以目覩名為眼見。常者，真實解脫之身，亦名眼見，亦名聞見」。初聞生信名為聞見，終證顯了說為眼見。

Below, the Buddha answers him: first, in response to the initial question, he distinguishes the characteristics of seeing them; from 'The body of the Tathāgata is of two kinds...' below, he resolves the subsequent objection, clarifying that they can be seen. In the former part, he first explains the characteristics of seeing the Tathāgata: 'The Buddha's bodies are of two kinds' briefly designates what is seen; 'permanent and impermanent' lists their two names; below, he demonstrates the characteristics of seeing them with reference to these two. The 'impermanent one is the body of manifestation and transformation expediously manifested to cross over sentient beings; it can be witnessed with the eye, and is called visual seeing. The permanent one is the body of true liberation; it is called visual seeing, and is also called auditory seeing.' Hearing it at first and giving rise to faith is called auditory seeing; ultimately realizing it clearly is called visual seeing.
