10.102

八者顯密一雙。初問答釋觀音名，明顯感密應。顯感者，謂眾生三業興感；密應者，觀音不現身、不說法而令得解脫也。普門即是密感顯應。顯應，觀察其心現身說法；密感者，不明眾生三業興感，但有應以言，謂根緣真發，故即為現身說法也。然顯密感應具通四句，可以意知也。初章明密應，後章明顯應，應章雖多不出顯密。今經正明感應，故四句之中但明期二也。非但此品明期義，乃總攝一切眾經應感義也。

Eighth is the pair of the manifest and the hidden. The first question and answer explains the name of Guanyin, clarifying manifest resonance and hidden response. Manifest resonance means sentient beings arouse resonance through the three karmas; hidden response means Guanyin delivers them without manifesting a body or expounding the Dharma. "Universal Gate" is hidden resonance and manifest response. As for manifest response, he contemplates their minds, manifests bodies, and expounds the Dharma; as for hidden resonance, it does not elucidate sentient beings arousing resonance through the three karmas, but merely states "should be delivered by...", meaning that spiritual capacities and conditions genuinely sprout, and so he immediately manifests bodies and expounds the Dharma for them. However, manifest and hidden resonances and responses fully comprise four propositions, which can be understood through reflection. The first section clarifies the hidden response, and the latter section clarifies the manifest response; although the response sections are many, they do not go beyond the manifest and hidden. The present sūtra precisely clarifies resonance and response; therefore, among the four propositions, it only clarifies these two. It is not only this chapter that clarifies this meaning; it completely subsumes the meaning of response and resonance across all sūtras.
