成唯識論掌中樞要 2.213

2.213

答：二理皆齊。前不放逸內異生福、不動唯種發故。經說言非無明發。若種亦不發，何得稱為非明為緣，非違有支，與見諦何別。由此故知，唯種亦發。問：若爾，何故生上初行支，不唯種發？有現無明為勝因，起遠真實義，愚現見有故，不同不放逸異生。

Answer: The reasons for both are equal. Because previously, the merit and immovable [karma] of unremiss ordinary beings within [the Dharma] are initiated merely by seeds, the sūtra states that they are not initiated by [manifest] ignorance. If seeds also did not initiate them, how could it be called 'conditioned by non-wisdom' without violating the limbs of existence, and how would it differ from seeing the truths? From this we know that mere seeds also initiate [karma]. Question: If so, why is the initial action limb born in the upper [realms] not initiated merely by seeds? Because active ignorance is the predominant cause, giving rise to [states] far from the real truth, and the delusion is evidently present, it is not the same as [that of] unremiss ordinary beings.
