念佛鏡 1.32

1.32

答曰：「一念、十念，為念數少，功德亦少，所以下品下生；一日、七日，為念數多，功德亦多，所以上品上生。又一念、十念，喻晚發心人；一日、七日，喻早發心人。所以一念、十念，一日、七日即生淨土，位居不退，直至無上菩提。

The answer states: "With one thought-moment or ten thought-moments, because the count of recitations is few, the merit is also small; therefore it is the lowest level of the lowest grade. With one day or seven days, because the count of recitations is many, the merit is also great; therefore it is the highest level of the highest grade. Furthermore, one thought-moment or ten thought-moments is an analogy for those who arouse the mind late; one day or seven days is an analogy for those who arouse the mind early. Therefore, whether in one thought-moment, ten thought-moments, one day, or seven days, one is immediately reborn in the pure land, abides in the stage of non-retrogression, and proceeds straight to unsurpassed bodhi.
