楞伽阿跋多羅寶經註解 2.155

2.155

自此之下問答有四：初問惑亂有無，因上以惑亂為常、為實，又以為妄想，然則果有耶？果無耶？佛答以如幻無計著相者，意謂若言妄法定有定無，則生計著性不可滅，故以如幻言之。若不能了如幻，則緣起之法同於外道邪計因緣矣。

From here below, there are four questions and answers. First is the question on the existence or nonexistence of delusion: because above delusion was treated as permanent and real, and also treated as vikalpa, is it then ultimately existent, or ultimately nonexistent? When the Buddha replies that it is like an illusion, without the lakṣaṇa of grasping, the intention is that if one asserts that false dharmas are definitively existent or definitively nonexistent, then grasping will arise and the svabhāva [of grasping] cannot be eliminated; therefore he speaks of it as like an illusion. If one cannot understand it to be like an illusion, then the dharmas of paratantra would become identical to the erroneous reckonings of causes and conditions by tīrthikas.
