羅睺（下胡釣反案字方言云一瞻也今云羅睺即梵語也或云攞護此云暗障能障日月之光即暗曜也）。

羅睺 (The second character has the fanqie hu + diao. Examining the character: the Fangyan says: “To glance at.” Now, Luohou is Sanskrit [Rāhu]; it is also written as 攞護; here translated as ‘Dark Obstructor’. It can obstruct the light of the sun and moon, hence it is a dark luminary.)
