佛說觀佛三昧海經 7.9

7.9

「爾時香烟至佛精舍，如白琉璃雲，繞佛七匝化作金蓋，其蓋有鈴出妙音聲，其聲請佛、請比丘僧。爾時如來勅諸比丘：『諸得六通者隨從佛後，受那乾訶羅王弗巴浮提請。』

"At that time the smoke of incense reached the Buddha's monastery like a cloud of white lapis lazuli. It circled the Buddha seven times and transformed into a golden canopy. The canopy had bells that emitted wondrous sounds, which invited the Buddha and invited the bhikṣu saṅgha. At that time the Tathāgata commanded the bhikṣus: 'All those who possess the six supernatural knowledges shall follow behind the Buddha to accept the invitation of King Phavabhati of Nagarahāra.'"
