觀無量壽佛經義疏 2.78

2.78

"'Within each jewel there are rays of light of five hundred colours; the light is like flowers, and also like stars and the moon hanging in empty space.'" The colourful lights of the numerous jewels: the light ascends from the ground into space, hence it is "like flowers"; it shines downward from above, hence it is "like stars and the moon." Third, combining these jewel-lights to form terraces and pavilions.
