阿彌陀經疏 1.67

1.67

舍利弗下，二、別示。又二：一、反顯；二、正示。初文不可以小善得生，則反顯可以多善得生也。小善謂等閑發願散亂善稱名，多善謂執持名號要期日限。

From "Śāriputra" onward, second, specific demonstration. This also has two parts: first, revealing through the negative; second, demonstrating directly. In the first text, [saying] that one cannot obtain rebirth through minor good roots negatively reveals that one can obtain rebirth through abundant good roots. Minor good roots refers to making vows casually and reciting the name with a scattered mind; abundant good roots refers to upholding the name firmly with a determined time limit.
