楞伽阿跋多羅寶經註解 1.602

1.602

"Mahāmati, I also, through such causal conditions, having seen that produced entities and non-entities are impermanent, state from the noble realm of self-realisation that their permanence is causeless. Mahāmati, if the tīrthikas were to establish permanence and incomprehensibility by causal lakṣaṇas, the nature and non-nature of their causal svalakṣaṇa would be identical to a hare's horns. This permanence and incomprehensibility would be merely verbal vikalpa. Those tīrthikas possess such faults. Why is that? Because it is merely verbal vikalpa identical to a hare's horns, and their own causal lakṣaṇa has no share [in reality]."
