金剛三昧經論 2.96

2.96

經曰　佛言：「常住涅槃是涅槃縛。何以故？涅槃本覺利，利本涅槃。涅槃覺分即本覺分，覺性不異，涅槃無異；覺本無生，涅槃無生；覺本無滅，涅槃無滅。涅槃本故，無得涅槃。涅槃無得，云何有住？善男子！覺者不住涅槃。何以故？覺本無生，離眾生垢；覺本無寂，離涅槃動。住如是地，心無所住，無有出入，入唵摩羅。」

The sūtra states: The Buddha said, “Permanently abiding in nirvāṇa is the bondage of nirvāṇa. Why is this? Nirvāṇa is the benefit of innate awakening; the root of benefit is nirvāṇa. The awakening-component of nirvāṇa is itself the component of innate awakening. The nature of awakening being non-different, nirvāṇa is non-different; awakening being originally unborn, nirvāṇa is unborn; awakening being originally unceasing, nirvāṇa is unceasing. Because nirvāṇa is the origin, there is no attaining nirvāṇa. If nirvāṇa is without attainment, how could there be abiding? Good son, the awakened one does not abide in nirvāṇa. Why is this? Awakening is originally unborn, far removed from the defilement of sentient beings; awakening is originally without tranquility, far removed from the stirring of nirvāṇa. Abiding on such a ground, the mind has nowhere to abide; there is no exiting or entering: one enters amala.”
