金光明經文句記 4.17

4.17

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.
