大般涅槃經義記 2.19

2.19

又問：倒想與前四住無明何別，而別請斷？解言：倒想是無明起，四住家因，故別請斷。云何得知？如《地持》說「如是如實，凡愚不知，起八妄想。」故知倒想是無明起，即彼宣說八種妄想能生見、慢、貪、恚、癡事，故知倒想是四住因。

Another question: How do inverted conceptions differ from the preceding four entrenchments and ignorance, such that they separately request their severance? Explanation: Inverted conceptions arise from ignorance and are the causes belonging to the four entrenchments; therefore they separately request their severance. How is this known? As the Bodhisattvabhūmi says: "Suchness as it truly is, ordinary fools do not know, and give rise to eight false conceptions." Thus we know that inverted conceptions arise from ignorance; and that very text explains that the eight false conceptions can give rise to matters of views, conceit, craving, anger, and delusion; thus we know that inverted conceptions are the causes of the four entrenchments.
