金剛三昧經論 1.126

1.126

經曰　「善男子！如是解脫法相皆無相行，亦無解不解，是名解脫。何以故？解脫之相無相無行，無動無亂、寂靜涅槃，亦不取涅槃相。」

The sūtra says: 'Good sons, such marks of liberation are all signless practice, and there is neither liberation nor non-liberation; this is called liberation. Why is this? The sign of liberation is without signs and without practice; it is without motion and without disturbance, quiescent nirvāṇa, yet it also does not grasp at the sign of nirvāṇa.'
