首楞嚴義疏注經 9.143

9.143

要除三惑者，此正勸也。前云「三緣斷故，三因不生，狂性自歇，歇即菩提」等。不盡下明不斷之失，修禪不持戒，是即魔羅業，以妄修於妄，真實可憐愍。汝妄下重指結答以示正邪也，前問云：此道為復本來自有？為是眾生妄習生起？今結答云：汝妄自造，非菩提咎。即以前句答後問，後句答前問也。

'You must eliminate the three delusions' is the direct exhortation. Earlier it was said: 'Because the three conditions are severed, the three causes do not arise; the frenzied nature spontaneously desists, and desisting is itself bodhi,' and so forth. From 'If you do not exhaust' onward, the fault of not severing them is explained: cultivating dhyāna without upholding the precepts is the work of Māra; cultivating falsity with falsity is truly pitiable. From 'Your falsity' onward, it reiterates and concludes the answer to show what is correct and what is deviant. The previous question asked: 'Does this path fundamentally exist of itself, or does it arise from the false habits of sentient beings?' Now the concluding answer states: 'Your falsity is created by yourself, not the fault of bodhi.' That is, the earlier sentence answers the latter question, and the latter sentence answers the earlier question.
