佛說觀彌勒菩薩上生兜率天經 1.17

1.17

爾時優波離即從座起，整衣服頭面作禮，白佛言：「世尊！兜率陀天上乃有如是極妙樂事，今此大士何時於閻浮提沒生於彼天？」

At that time, Upāli immediately arose from his seat, straightened his robes, bowed his head to the ground in reverence, and addressed the Buddha, saying: “World-Honoured One! In the Tuṣita Heaven there are such supremely wondrous and joyful matters; when will this Great Being pass away from Jambudvīpa and be born in that heaven?”
