仁王經疏 2.80

2.80

釋曰：第二、讚用。言金剛者，自有二義：一能斷智名為金剛，能斷一切諸煩惱故，今此經依此而說。二所斷惑名為金剛，性強難斷似金剛故，故新翻《般若》名為「能斷金剛」。惑可金剛亦屬能斷，由此義故，佛與菩薩同用此忍。

Explanation: The second [section] praises its function. Regarding 'vajra', it intrinsically has two meanings: First, the wisdom capable of severing is named vajra, because it can sever all afflictions; the present sūtra speaks relying on this. Second, the delusions to be severed are named vajra, because their nature is strong and hard to sever, resembling a diamond; therefore the newly translated *Prajñā[pāramitā]* is named 'Vajracchedikā' (Capable of Severing the Diamond). Alternatively, vajra may also pertain to that which is capable of severing. For this reason, buddhas and bodhisattvas both employ this patience.
