大方廣圓覺修多羅了義經略疏 2.574

2.574

Because all illusory realms are boundless and difficult to exhaustively investigate, it simply says "eliminate." Elimination means cutting off thoughts; functional actions would also obstruct meditative quiescence, hence it says "without adopting." The Sūtra on Entering the Realm of the Buddhas states: "All dharmas are like illusions; being like illusions, they cannot be grasped. Because one is free from all illusory dharmas, one pays homage to having nothing to contemplate."
