金剛三昧經論 2.80

2.80

經曰　無住菩薩言：「一切境空、一切身空、一切識空，覺亦應空。」佛言：「可一覺者不毀不壞，決定性非空非不空，無空不空。」

The sūtra says: Bodhisattva Apratiṣṭhita said, "If all objects are empty, all bodies are empty, and all consciousnesses are empty, awakening should also be empty."
The Buddha said, "All awakening is neither destroyed nor ruined. Its determinate nature is neither empty nor non-empty, devoid of emptiness and non-emptiness."
