成唯識論掌中樞要 2.138

2.138

要得根本定，煩惱方起，有依未至斷欲九品已，不得根本命終，此人以何現行潤生？有解：無此，必得，方命終故。如第七生預流，無命終不得應果者，心得根本定，方命終。有解：亦有唯以隨眠潤生，如見諦，以隨眠亦有現行潤故。此亦應爾。伏修，不伏見，見惑既不善，何不感惡趣而生上界耶？若以勢力不行，何不名伏？今以義解，由勢不行，不能發業。設使有者，輕而不重，非決定業，不感欲界生。若正六行所厭，名為伏故，不爾，便退。煩惱強故，定力勢劣弱故，以無修伴，弱故不能。

Only when one has attained the fundamental dhyāna do defilements then arise. If someone, relying on the preparatory [stage], having severed the nine grades of the desire realm, dies without having attained the fundamental [dhyāna], by what manifest activity does this person moisten rebirth? One explanation: this does not occur; one must attain it before dying. Just as with a stream-enterer in their seventh rebirth, none dies without having attained the fruit of arhatship; their mind attains the fundamental dhyāna and only then dies. Another explanation: it also occurs that one moistens rebirth solely through latencies (anuśaya), as with seeing the truths, because with latencies there is also moistening by manifest activity. This should also be like that. Subduing cultivation[-abandoned defilements] while not subduing seeing[-abandoned defilements]: since defilements of seeing are unwholesome, why do they not induce bad destinies rather than being born in higher realms? If because their power does not operate, why is it not called 'subdued'? Now explaining according to the principle: because their power does not operate, they cannot initiate karma. Even supposing there were some, it is light and not heavy, not a determinate karma, and does not induce rebirth in the desire realm. Only when one properly loathes through the six practices is it called 'subdued'; otherwise, one would fall back. Because defilements are strong and the force of dhyāna power is inferior and weak, lacking the companion of cultivation, being weak it is incapable.
