仁王般若經疏 1.68

1.68

十八梵天王雨百變異色華，六欲諸天雨無量色華。其佛座前自然生九百萬億劫華，上至非想非非想天。

The eighteen Brahmā heaven-kings rained down flowers of a hundred transformed, varied colors; the various devas of the six desire [heavens] rained down flowers of countless colors. In front of the Buddha's seat, flowers of nine hundred million kalpas spontaneously grew, ascending up to the heaven of neither-perception-nor-non-perception.
