金光明最勝王經疏 5.208

5.208

二釋名者，梵云仳[跳-兆+東]𪏭沙，此云無染著，舊云銀主者非也。所弘之法從最清淨法界平等所流，復由呪力能令離染無所住著，故云無染著。陀羅尼者，義如常辨。

Second, explaining the title: in Sanskrit it is called vidvaṃsa, which here is translated as "Undefiled." The old translation "Silver Master" is incorrect. The Dharma that is propagated flows equally from the most pure dharmadhātu; furthermore, through the power of the incantation, it can cause one to leave behind defilement and have no fixed abode or attachment; hence it is called "Undefiled." As for "dhāraṇī," its meaning is as usually explained.
