金光明最勝王經疏 6.219

6.219

下申讚。初標、次讚。此初也。於境專念云一心，尊重情深故合掌，身殊故異口，齊讚故同音。

Below, they express praise. First is the statement, next the praise. This is the first. Focusing mindful attention on the object is called "with one mind"; because their reverence is deep, they join palms; because their bodies are distinct, they have "different mouths"; because they praise in unison, they have "one voice".
