金光明經文句記 6.48

6.48

初、約破常答。凡夫四倒常樂我淨，顛倒之計託緣而成，故廢秋時，令諸弟子不保常樂。

First, answering in terms of breaking permanence. The four inversions of ordinary people are permanence, pleasure, self, and purity; inverted views are established by relying on conditions. Therefore autumn is eliminated, so that the disciples will not hold to permanence and pleasure.
