佛說觀佛三昧海經 6.52

6.52

時忉利宮滿中化佛，佛母摩耶頂上自然出眾供具，無量幢幡供養諸佛。時幢幡中有妙音聲，讚佛、讚法、讚比丘僧。

At that time, the Trāyastriṃśa palace was filled with transformation Buddhas. From above the head of Lady Māyā, the Buddha's mother, various offerings spontaneously emerged, with countless banners and streamers honoring all the Buddhas. From within the banners and streamers, wonderful sounds praised the Buddha, praised the Dharma, and praised the Sangha of monks.
