三彌勒經疏 1.93

1.93

經曰「佛告優婆離若有」以下，第三結勸生彼。生彼人雖無量，略有三類：一託勝所依為修妙行故，不厭生死者能生彼天，不同二乘厭生死苦也。二愛敬無上菩提心者能生彼天，為聞彌勒所說大法故，不同樂小果者也。三欲作彌勒弟子者也。生彼天者，修五因：一持五戒；二持八戒；三持具足戒，則出家五眾戒總名具戒，以沙彌戒亦近大戒故；四身心精進不求斷結；五修十善。如是修五因時，實一一思惟彼天上妙樂，迴向發願方能生也。

Where the sūtra states, "The Buddha told Upāli: 'If there are,'" onward: third, this concludes by encouraging rebirth there. Although persons born there are immeasurable, there are roughly three classes: First, those who rely on an excellent basis in order to cultivate marvelous practices; those who do not despise saṃsāra are able to be born in that heaven, unlike the two vehicles who despise the suffering of saṃsāra. Second, those who love and revere the unsurpassed bodhicitta are able to be born in that heaven in order to hear the great Dharma expounded by Maitreya, unlike those who delight in inferior fruits. Third, those who wish to become disciples of Maitreya. Those who are born in that heaven cultivate five causes: first, upholding the five precepts; second, upholding the eight precepts; third, upholding the complete precepts—that is, the precepts of the five renunciant assemblies are collectively called complete precepts, because the novice precepts also approximate the full precepts; fourth, bodily and mental vigor without seeking to sever the defilements; and fifth, cultivating the ten virtuous actions. When cultivating these five causes in this manner, only by truly contemplating one by one the supreme and marvelous delights of that heaven, dedicating merit, and making vows, will one be able to be born there.
