仁王般若經疏 3.39

3.39

爾時十六大國王聞佛所說十萬億偈般若波羅蜜，歡喜無量，即散百萬億行華，於虛空中變為一座，十方諸佛共坐一座說般若波羅蜜，無量大眾共坐一座，持金羅華散釋迦牟尼佛上，成萬輪華，蓋大眾上。

At that time, the kings of the sixteen great kingdoms, hearing the one hundred billion verses of prajñāpāramitā expounded by the Buddha, rejoiced immeasurably. They immediately scattered one trillion rows of flowers, which transformed in empty space into a single throne. The buddhas of the ten directions sat together on this single throne expounding the prajñāpāramitā, and the immeasurable great assembly sat together on this single throne. They held golden net flowers and scattered them over Śākyamuni Buddha, forming ten thousand wheels of flowers covering the great assembly.
