妙法蓮華經文句 10.107

10.107

「爾時妙音」下，第五，還本土。「動地雨花」者，菩薩經歷尚能傍益，況佛前放光，傍照東方百八萬億那由他土，亦傍論利益也。

From "At that time Gadgadasvara" onward is the fifth [section]: returning to his original land. As for "the earth shook and flowers rained down": if a bodhisattva's passing through can still provide collateral benefit, how much more so when the Buddha emits light before, collaterally illuminating one hundred and eight myriad koṭis of nayutas of lands in the east; this also collaterally discusses benefits.
