觀無量壽佛經疏 4.118

4.118

三、從或有眾生下至受苦無窮已來，正明第五第六門中簡機造惡輕重之相。即有其七。一明造惡之機。二明總舉不善之名。三明簡罪輕重。四明總結眾惡，非智人之業。五明造惡既多罪亦非輕。六明非業不受其報，非因不受其果，因業既非是樂，果報焉能不苦也。七明造惡之因既具酬報之劫未窮。

Third, the passage from "there may be sentient beings" down to "suffer boundless pain" directly clarifies, within the fifth and sixth gates, the characteristics of discerning capacity and the severity of evil created; herein there are seven points. First, it clarifies the capacity for creating evil. Second, it generally adduces the terms of unvirtuousness. Third, it distinguishes the gravity of offenses. Fourth, it generally concludes that manifold evils are not the deeds of wise persons. Fifth, it clarifies that as many evils have been created, the guilt is likewise not light. Sixth, it clarifies that without karma one suffers no retribution, and without a cause one experiences no effect; since the causal karma is not pleasant, how could the fruition not be painful? Seventh, it clarifies that since the causes of committing evil are fully present, the kalpas of repaying the retribution are without end.
