佛說觀彌勒菩薩上生兜率天經 1.15

1.15

佛告優波離：「此名兜率陀天十善報應勝妙福處。若我住世一小劫中，廣說一生補處菩薩報應及十善果者不能窮盡，今為汝等畧而解說。」

The Buddha said to Upāli: “This is called the place of superior and wondrous merit, the retribution of the ten good deeds in the Tuṣita Heaven. Even if I were to remain in the world for a minor kalpa to explain extensively the retributions of a bodhisattva bound to one last birth and the fruits of the ten good deeds, I could not exhaust them. Now I have explained them briefly for you all.”
