觀無量壽佛經義疏 3.237

3.237

「『命終之時，見金蓮華猶如日輪，住其人前。』」花如日輪者，喻其量也。若準《俱舍》日面徑五十一由旬。今此但取地居仰望，大小未必如論。三、得生。

"‘At the time of his death, he sees a golden lotus flower like the solar disk, resting before him.’" That the flower is like the solar disk illustrates its size. If according to the Abhidharmakośa, the solar face has a diameter of fifty-one yojanas. Here it is taken merely from the perspective of an earthly dweller looking up; its size is not necessarily as described in the treatise. Third, attaining rebirth.
