首楞嚴義疏注經 10.31

10.31

「阿難！是三摩中諸善男子，凝明正心，魔不得便。窮生類本，觀彼幽清常擾動元，於圓常中起計度者，是人墜入四遍常論。」

"Ānanda, when all these good sons in samādhi keep their correct minds concentrated and bright, māras can find no advantage against them. Exhaustively probing the origin of the categories of living beings, they contemplate that hidden, clear, and constantly fluctuating source of motion. If they form calculations regarding pervasive permanence, they will fall into the four theories of pervasive permanence."
