“蔼沬”一词,道教文献中注解有两处,让人莫衷一是。原因在于文献中“沬”与“沫”写法上的混同,通过对文本的分析,我们认为“蔼沬”释为“昏暗貌”更为恰当。“乙密”一词,许多学者做过讨论。结合道教文献用例,可以确定“乙密”是“乙”与“密”构成的同义复合词,表“精微,隐密”之义。 “Amity ” word, there are two notes in the Taoist literature, it is incomprehensible. The reason is that in the literature, “沬” and “” written on the confusion, through the analysis of the text, we think “蔼 沬 ” interpreted as “dim appearance ” more appropriate. “B-secret”, many scholars have discussed. Combining the Taoist literature use cases, we can confirm that “Bami” is a synonymous compound of “B” and “Mi”, with the meaning of “subtle and implicit”.
