法華玄論 6.33

6.33

答：具有二義。一者索許名索，謂三乘人索果義也。若以求索名索，大機既動，扣佛說於一佛乘，故有未許名索也。此就言許及言未許，故作斯判。若言意合論者，皆是許也，言許於三，是故索三；意許於一，所以索一。亦是顯密二許，顯密二索，顯許其三、密欲與一。言顯索三機、密索一也。

Answer: It possesses both meanings. First, asking for what was promised is called asking, referring to the meaning of the people of the three vehicles asking for the fruit. If seeking and requesting is called asking, then since the Mahāyāna capacity was stirred, knocking upon the Buddha to preach the one Buddha-vehicle, there is asking for what was not promised. This distinction is made based on whether there was an explicit promise or not. If one discusses the words and the intention in combination, both are promises: the words promised the three, and therefore they asked for the three; the intention promised the one, and for that reason they asked for the one. This is also the twofold promise—explicit and implicit—and the twofold asking—explicit and implicit. Explicitly he promised the three; implicitly he wished to grant the one. In words, they explicitly asked for the three capacities; implicitly, they asked for the one.
