金光明最勝王經疏 5.431

5.431

下讚佛語等為請所由。初讚實語、次讚語具、後讚利益。讚語有三：初讚因、次「已於」下讚果、後「有實語者」下讚隨喜。明世尊等有喜無量，不嫉生得，故請加被。

Below is praising the Buddha's speech and so forth as the ground for the invocation. First it praises true words; next it praises the instrument of speech; later it praises the benefits. Praising speech has three parts: first, praising the cause; next, from "already for" downward, praising the result; later, from "whoever speaks true words" downward, praising the rejoicing with joy. This shows that the World-Honoured One and others have the immeasurable state of sympathetic joy, without jealousy toward what beings attain; therefore one invokes their empowerment.
