仁王經疏 1.175

1.175

釋曰：第五、思緣現瑞。文別有五：一思緣放大光、二頂上出華、三諸天雨華、四佛華自生、五大地六動。此即初也。謂今世尊思緣放光，照三界中。又解：思緣屬上段也。

Explanation: Fifth, contemplating conditions and manifesting the auspicious signs. In the text there are five distinct parts: first, contemplating conditions and emitting a great light; second, flowers emerging from the crown of the head; third, the devas raining flowers; fourth, the Buddha's flowers spontaneously growing; fifth, the six kinds of shaking of the great earth. This is the first. It means that now the World-Honoured One contemplates the conditions and emits light, illuminating within the three realms. Another interpretation: "contemplating conditions" belongs to the preceding passage.
