金剛般若波羅蜜經註解 1.101

1.101

善現解佛問意，即答以無道可證、無法可說。「何以故」下又自徵釋，由不可取、不可說，非法、非非法。

Subhūti understood the intent of the Buddha's question, and immediately answered that there is no Way to be realized and no Dharma to be spoken. Under 'Why is this?' he further investigated and explained on his own: because they are ungraspable and ineffable, neither dharmas nor non-dharmas.
