觀無量壽佛經義疏 3.240

3.240

「『觀世音、大勢至以大悲音聲，為其廣說諸法實相，除滅罪法。』」罪從緣生，無有自性。諸法皆爾，故名實相。普賢行法云「一切業障海，皆從妄想生。若欲懺悔者，端坐念實相」是也。三、聞法獲益。

"‘Avalokiteśvara and Mahāsthāmaprāpta, with voices of great compassion, extensively expound for him the true mark of all dharmas and the method for eradicating sins.’" Sins arise from conditions and lack intrinsic nature. All dharmas are like this; hence it is called the true mark. As the Method of Practicing the Samantabhadra [Contemplation] states: "The ocean of all karmic hindrances arises entirely from false discrimination. If one wishes to repent, sit upright and be mindful of the true mark." This is what it refers to. Third, hearing the Dharma and gaining benefits.
