妙法蓮華經玄贊 9.157

9.157

釋妨難者，問：此品亦明解寶珠事，何故不為品名？答：因明勝行讚經勝德，非欲對機正明珠事，故但以此安樂行為名。

Resolving difficulties: Question: This chapter also clarifies the matter of untying the precious gem; why is it not named after that? Answer: Because it clarifies superior practice to praise the superior virtue of the sūtra, not intending primarily to clarify the matter of the gem for the sake of the audience's capacity; therefore it is solely named after these peaceful practices.
