阿彌陀經疏 1.239

1.239

問：「已發願、今發願可令得不退轉，當發願者既未發願，云何得言得不退轉？」

Question: 'For those who have already made the vow or are now making the vow, it is plausible to let them attain non-retrogression. But for those who will make the vow, since they have not yet made the vow, how can it be said that they attain non-retrogression?'
