楞伽阿跋多羅寶經註解 1.604

1.604

「大慧！我常不思議因自覺得相故，離所作性，非性故常，非外性非性無常，思量計常。大慧！若復外性非性無常，思量計常、不思議常，而彼不知常不思議自因之相，去得自覺聖智境界相遠，彼不應說。」

"Mahāmati, my permanence and incomprehensibility, because their lakṣaṇa is attained through self-realisation, are free from produced being and, because they are non-being, are permanent; they are not like the external being and non-being that are impermanent, which are mentally deliberated and constructed as permanent. Mahāmati, if there are further external beings and non-beings that are impermanent, which are mentally deliberated and constructed as permanent and incomprehensibly permanent, yet they do not know the lakṣaṇa of the intrinsic cause of permanence and incomprehensibility and are far from attaining the realm and lakṣaṇa of pratyātmāryajñāna, they should not speak [of it]."
