俱舍論記 11.53

11.53

「日月徑量至為益為損」者，釋第二句，兼顯星量。日、月二體隨有情業增上所生，能於眼等為益為損。如遇日光，眼見諸色，身冷得暖，果熟、花開，稼穡等物皆得成熟，此即為益。或如遇日光不能見色，蝙、蝮等，患熱身損，果壞、花萎，稼穡等物皆悉枯槁，此即為損。如遇月光，蝙、蝮等眼能見諸色，身熱得涼，果熟、花開，稼穡等物皆得成熟，此即為益。或遇月光不能遠見色如人等眼，患冷身損，果壞、花萎，稼穡等物皆悉枯槁，此即為損。損、益不同，故言如其所應為益為損。

Regarding the passage from "The diameter of the sun and moon" up to "bring benefit or harm": Explaining the second line, and additionally revealing the size of the stars. The two physical bodies of the sun and moon arise through the sovereign force (*adhipati*) of sentient beings' karma, and they can bring benefit or harm to the eyes and other faculties. For instance, when encountering sunlight, eyes see visible forms, cold bodies gain warmth, fruits ripen, flowers bloom, and crops and grain all mature; this is benefit. Or, when encountering sunlight, some creatures cannot see forms, such as bats and vipers; they suffer from heat, their bodies are harmed, fruits rot, flowers wither, and crops and grain completely desiccate; this is harm. When encountering moonlight, the eyes of bats, vipers, and the like can see forms, hot bodies find coolness, fruits ripen, flowers bloom, and crops and grain all mature; this is benefit. Or, when encountering moonlight, creatures cannot see forms at a distance, such as the eyes of humans; they suffer from cold, their bodies are harmed, fruits rot, flowers wither, and crops and grain completely desiccate; this is harm. Because harm and benefit are not uniform, it says "bringing benefit or harm as appropriate."
