娜（此字梵音有鼻聲應書曩字取上聲兼鼻音即是已上五字正是五髻文殊五字真言也）。

[Sanskrit syllable] na (娜: this character in Sanskrit pronunciation has a nasal sound; one should write the character 曩, taking the rising tone together with a nasal sound, which will be correct. The above five syllables are precisely the five-syllable mantra of Five-Chignon Mañjuśrī).
