法華義疏 12.191

12.191

品開為三：第一、對藥王說經福重；二、眾人說呪擁護；三、時眾得益。初文又二：前問、後答。所以說經福重者，有二種義：一、欲令人欣福持經；二、明持經福重，故次說呪護之。

The chapter is divided into three: first, speaking to Bhaiṣajyarāja on the gravity of the merit of the sūtra; second, the assembly speaking incantations for protection; third, the assembly at that time gaining benefit. The first section also has two parts: first the question, then the answer. As for why the gravity of the merit of the sūtra is spoken of, there are two meanings: first, wishing to make people rejoice in the merit and uphold the sūtra; second, clarifying that the merit of upholding the sūtra is grave, therefore next incantations are spoken to protect them.
