金剛經纂要刊定記 2.147

2.147

體性無別者，皆別境中一也。前三種智皆名慧故，故智與慧皆如金剛。故《薩遮尼乾經》云：「帝釋金剛寶能滅阿修羅，智碎煩惱山，能壞亦如是。」《無常經》云：「金剛智杵碎邪山，永斷無始相纏縛。」

As for "their essential nature has no difference," both are one among the particular-object [mental factors]. Because the former three kinds of knowledge are all named wisdom, knowledge and wisdom are both like a vajra. Therefore the Satyakanirgrantha Sūtra says: "Śakra's vajra jewel can destroy the asuras; knowledge crushes the mountain of afflictions, and its ability to destroy is also like this." The Anityatā Sūtra says: "The vajra knowledge-pestle crushes the mountain of heresy, forever severing beginningless mutual entanglements."
