首楞嚴義疏注經 10.19

10.19

止觀增勝，想念不起，故云凝明正心。欲界愛染不生，故云魔不得便。於此推窮生類之本，唯一行陰幽隱清虛，以為一切生滅之元。今既披露，此外更無眾生之本，便執世間無因而起，以不知善惡因由、差別種子在識陰故。即外道論因此而有，皆修行至此，邪慧忽生，名為見發，非是本來別有外道。

As śamatha and vipaśyanā grow superior, thought-concepts do not arise; hence it is said, "keep their correct minds concentrated and bright." Because passionate craving in the desire realm does not arise, it is said that the māras find no advantage against them. Here they infer and exhaustively probe the origin of the categories of living beings, finding only the single aggregate of volitional formations, hidden and clear, to be the source of all arising and ceasing. Now that it is laid bare, with no other origin of sentient beings besides this, they then cling to the idea that the world arose without a cause, because they do not know that the causal origins of good and evil and the differentiated seeds reside in the aggregate of consciousness. That is, the treatises of externalists arose on account of this. In all cases, when practitioners reach this point, deviant wisdom suddenly arises; this is called "the eruption of views," and not that there were distinct externalists originally.
