注大乘入楞伽經 8.79

8.79

言佛是常是無常，俱有過咎。云何有過咎？若如來常者，則同外道計神我等為能作者，為能作常。若無常者，則同世間有為作法，為相所相，畢竟敗壞成於無有，法身應斷滅。然佛如來實非斷常。

To state that the Buddha is permanent or impermanent both entails fault. Why does it entail fault? If the Tathāgata were permanent, he would be identical with the non-Buddhists who grasp at an ātman and so forth as a creator, positing a permanent creator. If he were impermanent, he would be identical with conditioned, fabricated phenomena of the mundane world, characterized by signs and their signifiers, ultimately decaying into nonexistence, and the Dharmakāya would be annihilated. Yet the Buddha, the Tathāgata, is truly free from annihilation and permanence.
