法華玄論 6.73

6.73

答：下合譬中云「若見無量億千眾生以佛教門出三界苦得涅槃樂，便賜大車。」此約羅漢非一，故有諸子耳。又雖無緣覺，懸為緣覺果人作索車譬，合緣覺因人領解，亦義無失也。又即以此文證無菩薩索車義。但羅漢一人即得索三，豈須三人方索三耶？

Answer: Below, in the matching of the parable, it says: "If he sees that immeasurable hundreds of thousands of myriads of sentient beings, by means of the Buddha's teaching gate, have exited the suffering of the three realms and attained the joy of nirvāṇa, he then bestows the great carriage." This refers to arhats not being one, hence there are "sons." Furthermore, although there were no pratyekabuddhas present, implicitly constructing the parable of demanding the carriages for persons of the pratyekabuddha fruit, and matching it with persons at the causal stage of the pratyekabuddha gaining an understanding, is also doctrinally without fault. Moreover, one precisely uses this text to prove that there is no doctrine of bodhisattvas demanding the carriages. The single person of the arhat is already sufficient to demand the three; why must there be three kinds of persons before demanding the three?
