「謂證初地菩提故」下。第二釋經。就文為三：一就位釋、二解八生一生、三與異人諍經。

From "refers to realizing the bodhi of the first bhūmi" onward, second is explaining the sūtra. In the text there are three [parts]: first, explaining in terms of the stage; second, explaining "eight rebirths and a single rebirth"; third, debating the sūtra with other teachers.
