金光明最勝王經疏 2.17

2.17

問：文中既有總別不同，涅槃何故不如三身別品？答：以文少故、事相同故，合為一品。

Question: Since the text has general and specific differences, why is nirvāṇa not treated in a separate chapter like the three bodies? Answer: Because the text is brief and the matters share the same characteristics, they are combined into a single chapter.
