3.59

經「過去至怖畏」，明果由因也。一切苦，即穀貴等苦果也。若由過去所感，即成順生、順後二報；若由現惡所感，即成順現報。經「如火燒薪」者，《涅槃》明少善能除大惡，譬如少火能燒一切。經「三毒等畏」者，即等分煩惱，并上是四分。

The sūtra's "from the past to fears" clarifies that effects arise from causes. "All sufferings" refers to suffering effects such as famine. If stimulated by the past, they become retributions to be experienced in the next life or in subsequent lives; if stimulated by present evil, they become retributions to be experienced in the present life. The sūtra's "like fire burning firewood": the Nirvāṇa explains that a small amount of good can eliminate great evil, just as a small fire can burn everything. The sūtra's "fears of the three poisons and so forth": these are the afflictions of equal parts, which, together with the above, make four parts.
