3.185

"Yet your treatise states: 'Beyond existence and non-existence there is separately a marvelous path; being marvelous beyond existence and non-existence, it is called nirvāṇa.' Please let us examine the fundamental substance of this marvelous path: if it is indeed existent, though marvelous, it is not non-existent. Though marvelous, if it is not non-existent, it enters the realm of existence. If it is indeed non-existent, being non-existent, it has no differentiation. Being non-existent and without differentiation, it enters the realm of non-existence. Comprehensively gathering it and investigating it directly, it is clear that there is no non-non-existence that is distinct from existence, and no non-existence that is distinct from non-existence.
