或前二十九頌宗明正因相，顯非常故；後之一頌宗明正果相，顯非斷故。以佛正法因果為宗，破彼常斷故。今應說總為二段，因相有二：初二十五頌宗明因體，未趣入故；次之四頌宗明因位，已發趣故。因體之中，前二十四頌明世俗因；次有一頌明勝義因，性、相亦爾。或初一頌半略明因；後二十三頌半廣明因。標釋亦爾。

Or [it may be held that] the first twenty-nine verses primarily clarify the aspect of the correct cause, revealing non-permanence; while the final one verse primarily clarifies the aspect of the correct effect, revealing non-annihilation. Taking the cause and effect of the Buddha's true Dharma as the central theme, they shatter those [views of] permanence and annihilation. Now, it should be said that altogether there are two sections, and the aspect of cause has two [parts]: the first twenty-five verses primarily clarify the substance of the cause, because one has not yet entered [the path]; the next four verses primarily clarify the stages of the cause, because one has already embarked. Within the substance of the cause, the first twenty-four verses clarify conventional causes; the next one verse clarifies the ultimate cause; nature and characteristics are also like this. Or, the first verse and a half briefly clarifies the cause, and the latter twenty-three and a half verses broadly clarify the cause; designation and explanation are also like this.
