金剛三昧經論 1.125

1.125

論曰：此下第二總明。於中有二：先明六度同一解脫、後顯解脫即是涅槃。初中言皆獲本利入決定性者，六度始修皆同本覺，本覺顯成本利行故。入如來藏性本寂靜無始無終，無改轉故。如是六度得本利故，遠離妄念流轉之相，故曰超然出世。入法性故周遍法界，無相無為無縛無脫，故曰無礙解脫。

The treatise says: Below this is the second [section], an overarching explanation. Within it there are two: first, explaining that the six perfections share the same liberation; next, revealing that liberation is precisely nirvāṇa. In the first, as for 'all obtain the original benefit and enter into the determinate nature', the initial practice of the six perfections is entirely identical with innate awakening, because innate awakening manifests to accomplish the practice of original benefit. Entering the tathāgatagarbha, its nature is originally quiescent, without beginning and without end, and without change or transformation. Because the six perfections thus obtain the original benefit, they leave far behind the signs of the transmigration of delusive thoughts; hence it is said, 'transcendently go beyond the world'. Because they enter the dharma-nature, they pervade the dharma-realm; they are signless, unconditioned, unbound, and unfreed; hence it is called 'unhindered liberation'.
