佛祖統紀 34.8

34.8

菩薩從兜率天將降神時。有十佛剎微塵數菩薩。皆與菩薩同願同行。乃至普賢神通行願。悉皆同等（華嚴經）。

When the bodhisattva was about to descend his spirit from the Tuṣita Heaven, there were bodhisattvas as numerous as the dust motes of ten Buddha-lands who all shared the same vows and practices as the bodhisattva, and even their supernatural powers, practices, and vows were entirely equal to Samantabhadra's (Avataṃsaka-sūtra).
