大方廣圓覺修多羅了義經略疏 1.22

1.22

發業成種，無明為根，潤業受生，貪愛為本。若不識其相，賊即能為；若不達其空，永不可斷。故答文殊、彌勒究了，盡其根源。

Generating karma to form seeds has ignorance as its root; nourishing karma to receive rebirth has craving and attachment as its basis. If one does not recognize their characteristics, they can act as thieves; if one does not comprehend their emptiness, they can never be severed. Therefore the answers to Mañjuśrī and Maitreya investigate them thoroughly and exhaust their root source.
