注大乘入楞伽經 3.82

3.82

若外道以如是無常因相，成常不思議者，此因相非真實故同於兔角，故常不思議唯是妄想言說。何以故？無有常因常相故。

If the heterodox, through such causal characteristics of impermanence, establish the permanent and inconceivable, these causal characteristics are not real and are therefore like the horns of a hare; thus their permanent and inconceivable is merely a verbal expression of false discrimination. Why is that? Because it lacks a permanent cause and permanent characteristics.
