1.166

謂謗因果作用實事者。言謗因者。謂無施與無愛養無祠祀無惡行無妙行。言謗果者。謂無惡行無妙行所感異熟果等。謗作用者。無此世間無彼世間無父無母。壞實事者。謂無世間真阿羅漢。即是因果皆空宗也。

As for "repudiating cause and effect, function, and real entities": saying that one repudiates cause means [asserting that] there is no giving, no caring/fostering, no sacrificial offering, no bad conduct, and no good conduct. Saying that one repudiates effect means [asserting that] there are no vipākaphala and so forth brought about by bad conduct or good conduct. Repudiating function means [asserting that] there is no this world, no other world, no father, and no mother. Destroying real entities means [asserting that] there are no true arhats in the world. This is the doctrine that cause and effect are both empty.
