大般涅槃經疏 18.17

18.17

「云何念法」下，第二念。舊云二：先念別體法；「唯此正法」下，念一體法。今不爾。文云「最上最妙，能令眾生得現在果。」若準藏通，能得現果而非上妙，別是上妙而非現果，動經無量阿僧祇劫。唯圓上妙能得現果，當知是圓一體之法。

From "How does one recollect the Dharma?" downward is the second recollection. Ancient commentators said there are two: first, recollecting the Dharma of distinct essence; from "Only this true Dharma" downward, recollecting the Dharma of identical essence. Now we say this is not so. The text says: "Supreme and most wonderful, able to cause sentient beings to attain the present result." If judged by the Tripiṭaka and Shared teachings, they can attain the present result but are not supreme and wonderful; the Distinct teaching is supreme and wonderful but does not attain the present result, easily taking immeasurable asaṃkhyeya kalpas. Only the supreme and wonderful of the Perfect teaching can attain the present result; one should know this is the Dharma of identical essence of the Perfect [teaching].
