24.114

第七解記別門，言又諸如來，善避他論等者，泰師等云：一、外道問神我等，是定不應記法，然彼作不定問言神我與身為一為異，如來默答避之；二、於喜樂與色等別義法，是決定應記別法而作一異不定問；又喜樂與諸四取煩惱義別作不定問，如來皆能避之。

Seventh, it explains the gate of declaration. Regarding "Furthermore, the Tathāgatas are adept at avoiding the arguments of others, etc.": Master Tai and others say: "First, when non-Buddhists ask about the self and so forth, these are dharmas that definitely should not be declared; yet they ask an indefinite question, saying 'is the self identical to or different from the body?' and the Tathāgata responds with silence to avoid it. Second, regarding dharmas with distinct meanings like joy and pleasure versus matter and so forth, which are dharmas that definitely should be declared, they ask an indefinite question about identity and difference; furthermore, when they ask an indefinite question about the distinct meanings of joy and pleasure versus the four graspings and afflictions, the Tathāgata is able to avoid them all."
