2.127

鞞麼（上音毘下音莫可反自獶鉢彌至鞞麼皆真言中字但借音就字影對梵聲不求訓釋也）。

鞞麼 (the first character is pronounced like 毘 [pí]; the second is pronounced *m[ò]-k[ě]* fan. From 獶鉢彌 to 鞞麼, all are characters in mantras; they merely borrow sound through characters to reflect Sanskrit sounds, without seeking glosses or explanations).
