大般涅槃經集解 18.205

18.205

案僧亮曰：受屈於邪，言謂之沒也。有名無實，譬之膚也。法瑤曰：正信微淺，不能自固，遂同說耶見也。僧宗曰：信為不信所陵，圓解則隱也。寶亮曰：佛弟子以相心說無相，理既無相，幽而難顯。外道以相心說相，理則易安，經生死久，遂失本解。逐彼邪計故，言沒膚中也。道慧記曰：所以言膚中者，明非永失，尋發不久也。

Sengliang states: Being overcome by the deviant is called sinking. Having a name without reality is compared to the flesh. Fayao states: Correct faith is slight and shallow, unable to maintain itself firmly, so one eventually comes to speak deviant views as well. Sengzong states: Faith being encroached upon by unfaith, the complete understanding is concealed. Baoliang states: Disciples of the Buddha, with a mind attached to characteristics, speak of the formless; since the principle is formless, it is profound and difficult to manifest. Non-Buddhists, with a mind attached to characteristics, speak of characteristics; the principle is then easily accepted. Transmigrating long through saṃsāra, they eventually lose their original understanding. Following those deviant reckonings, it is therefore said that it sank into the flesh. Daohui's Record states: The reason it says 'into the flesh' is to clarify that it is not permanently lost, but will quickly emerge before long.
