6.127

三界冥（下莫經反又莫定反爾雅晦也切韻暗也夜也說文云月從十六日始冥故字從六日冖音覓聲也亦覆蓋之形也經從水作溟即溟濛小雨皃又溟海也非冥暗也又有從宀具作𡨋非本字宀音莫仙反）。

Darkness of the three realms (三界冥: the second [character] is *ming*, fanqie 莫經, also fanqie 莫定. The Erya says: 'Dim.' The Qieyun says: 'Dark; night.' The Shuowen jiezi says: 'The moon begins to grow dark from the sixteenth day, hence the character is composed of 六, 日, and 冖, with 冖 pronounced *mi* as phonetic; it also has the shape of covering.' In the sūtra it is written with the water radical 水 as 溟, which means the appearance of a light drizzle, or an ocean, not darkness. There is also a form composed of 宀 and 具 as 𡨋, which is not the standard character; 宀 is pronounced fanqie 莫仙).
