仁王護國般若波羅蜜多經疏 1.154

1.154

解曰：身諸毛孔者，為欲說經故先入定，為驚凡聖現瑞放光。從佛足輪上至于頂，遍身毛孔皆流照故。普照十方恒沙佛土者，有緣斯現，即所照也。從此第三雨花供養。文分為二：初明欲色、後明無色。初文復三：且初第一欲界雨花。

Exposition: 'From all the pores of his body': wishing to preach the sūtra, he first entered samādhi; to startle both ordinary beings and noble ones, he manifested a portent and emitted light. From the wheel-marks on the Buddha's feet up to the crown of his head, all the pores of his entire body flowed with illumination. 'Universally illuminating the buddha-lands as numerous as the sands of the Ganges in the ten directions': wherever there were [receptive] conditions, [the light] appeared there; this refers to what was illuminated. Hereafter follows the third section, the rain of flowers as an offering. The text is divided into two: first, explaining the desire and form [realms]; second, explaining the formless [realm]. The first text again has three parts: first, the raining of flowers from the desire realm.
