金光明經文句記 4.17

4.17

三、「奉貢」下，同求記莂願。以鼓必具圓空鳴義，今讚如來一體三身，名為金鼓讚佛因緣。以此因緣趣向果地，名為奉貢，不論事相金鼓形也。

Third, from 'respectfully offering' onward is the vow to seek vyākaraṇa together. Because the drum necessarily possesses the meaning of sounding complete emptiness, now praising the Tathāgata's three bodies of one substance is called the cause and condition of praising the Buddha with the golden drum. By means of this cause and condition one proceeds toward the fruit-ground; this is called 'respectfully offering', not referring to the phenomenal aspect of the physical shape of the golden drum.
