妙法蓮華經玄贊 5.116

5.116

贊曰：下第六法住短長，有四：一佛壽，二生壽，三授當佛記，四記正像法。此初二也。釋迦眾生薄福少慧，佛壽故短、生壽故長，留殘第五分壽施未來弟子；華光如來所化眾生，福慧自脩不假佛與，故佛壽長、眾生壽短。又釋迦眾生薄福無感，故佛壽短，不感佛故；華光眾生多福有感，故佛壽長，感佛化故。

The Eulogy says: Below, the sixth [part] is the length of the duration of the Dharma, which has four parts: first, the Buddha's lifespan; second, sentient beings' lifespan; third, bestowing the prophecy of the future buddha; fourth, prophesying the true and semblance Dharmas. Here are the first two. Sentient beings under Śākyamuni have meager merit and little wisdom, so the Buddha's lifespan is short while sentient beings' lifespan is long, leaving the remaining fifth part of his lifespan to bestow upon future disciples; the sentient beings transformed by Padmaprabha Tathāgata cultivate merit and wisdom on their own without relying on the Buddha's bestowal, so the Buddha's lifespan is long while sentient beings' lifespan is short. Moreover, Śākyamuni's sentient beings have meager merit and lack resonance, so the Buddha's lifespan is short because they do not resonate with the Buddha; Padmaprabha's sentient beings have much merit and possess resonance, so the Buddha's lifespan is long because they resonate with the Buddha's transforming work.
