金剛般若經贊述 2.219

2.219

問：「若爾者，何故前言『應化非真佛，亦非說法者』耶？」答：「彼推功歸本故，要內證真說，於外可能說，所以喚法身無說，是真說也。」

Question: "If that is so, why was it said earlier that 'the responsive and transformed [bodies] are not the true Buddha, nor are they the teacher of the Dharma'?" Answer: "That traces the function back to the source; one must inwardly realise the true teaching before one can speak externally. Therefore, calling the dharmakāya 'without speech' is the true teaching."
