妙法蓮華經玄義 10.27

10.27

難第五時教，雙林常住，眾生佛性，闡提作佛者，問成論師，依二諦解義，第五時教為二諦攝不？若二諦攝，與諸教同，前教二諦猶是無常，雙林二諦何得是常？若雙林不出二諦，能照別理，破別惑，得是常者；前教所明二諦，亦照別理，破別惑，那忽無常？眾生佛性，闡提作佛，例如此難。故知明理不異前時，據何為常住耶？

Challenging the teaching of the fifth period—the eternal permanence in the Twin Groves, the buddha-nature of sentient beings, and icchantikas becoming buddhas: I ask the Satyasiddhi masters: according to your interpretation of the meaning based on the two truths, is the teaching of the fifth period subsumed under the two truths or not? If it is subsumed under the two truths, it is identical with the other teachings; if the two truths of the prior teachings are still impermanent, how could the two truths of the Twin Groves be permanent? If the Twin Groves do not go beyond the two truths, yet are able to illuminate a distinct principle and destroy distinct delusions so as to be permanent, then the two truths clarified in the prior teachings also illuminate a distinct principle and destroy distinct delusions—why then would they be impermanent? The buddha-nature of sentient beings and icchantikas becoming buddhas are challenged similarly to this. Therefore we know that the principle it clarifies is no different from the previous period; on what basis then is it considered eternally abiding?
