佛說觀佛三昧海經 7.19

7.19

「爾時世尊出金色臂張合曼掌，指網曼間雨大寶花，大眾皆見化成化佛，唯諸龍見是金翅鳥欲搏噬龍，龍畏金翅走入佛影，為佛作禮叩頭求救。佛至縵前勅阿難言：『敷尼師檀。』是時阿難即入縵中，先舉右手從左肩上取尼師檀。時尼師檀即復化成五百億金臺，七寶挍飾，欲敷之時即復化成五百億蓮華七寶莊嚴。政四角時，一角生五百億七寶蓮華，行行相次遍滿縵內。

"Then the Bhagavat extended his golden arms and spread his webbed palms; from between his webbed fingers rained down great jeweled flowers. The great assembly all saw them transform into transformation Buddhas, while only the nāgas saw them as garuḍa birds wishing to seize and devour the nāgas. Terrified of the garuḍas, the nāgas fled into the Buddha's shadow, paid homage to the Buddha, and knocked their heads begging for rescue. When the Buddha reached the front of the canopy, he instructed Ānanda: 'Spread the niṣīdāna.' Ānanda then entered the canopy, first raising his right hand to take the niṣīdāna from his left shoulder. That niṣīdāna immediately transformed into fifty billion golden terraces adorned with the seven treasures; when he went to spread it, it immediately transformed into fifty billion lotus blossoms adorned with the seven treasures. When he adjusted the four corners, from each corner sprang fifty billion lotus blossoms of the seven treasures, row upon row filling the inside of the canopy.
