3.125

「『如先所說，無量壽佛身量無邊，非是凡夫心力所及。然彼如來宿願力故，有憶持者必得成就。』」先所說者，指前佛觀。凡夫心劣雖不能觀，仗佛願力有想必成。三、舉像況真。

"‘As previously explained, the physical dimensions of Amitāyus Buddha are boundless, beyond the reach of the mental power of ordinary beings. However, by the power of that Tathāgata's past vows, those who remember and retain it are certain to attain accomplishment.’" "As previously explained" points back to the earlier contemplation of the Buddha. Although the inferior mind of ordinary beings cannot contemplate it, by relying on the power of the Buddha's vows, whenever there is visualization, it will certainly succeed. Third, citing the image to illustrate the reality.
