妙法蓮華經玄義 5.93

5.93

若歷三藏教中，凡夫及方便位，及菩薩位，聞三藏教，於中即能密見中道，即是乳中殺人。若四果位，密見中道，即是酪中殺人。顯露教中，無此事也。

If one traverses the tripiṭaka teaching, when ordinary persons, those in the provisional stages, and those in the bodhisattva stage hear the tripiṭaka teaching and within it are able secretly to see the middle path, this is killing in milk. If those in the stages of the four fruitions secretly see the middle path, this is killing in curdled milk. In the explicit teaching, there is no such thing.
