法華論疏 2.436

2.436

「從何等為四」已下，第二別釋四義，即成四別。就釋開義為三：一者標章略釋、二引經、三釋經。「一者無上義」，標章。

From "what are the four" onward is the second part, separately explaining the four meanings, which form four distinct divisions. In explaining the meaning of "opening," there are three parts: first, presenting the heading and briefly explaining it; second, quoting the sūtra; third, explaining the sūtra. "First is the unexcelled meaning" presents the heading.
