羅睺（睺胡搆反羅此云攝睺云惱也修羅能隱攝日月光明令中諸天生苦惱也或曰羅虎那此云名普聞謂日月普天照臨此既蔽之故天下聞其名也）。

Rāhu (羅睺: 睺 is pronounced with the fanqie 胡搆 [hòu]. 'Rā' here means 'to take' or 'seize'; 'hu' means 'to vex'. This asura can obscure and seize the radiance of the sun and moon, causing the devas within them to suffer distress. Or it is called Rāhuṇa, which is translated here as 'fame heard everywhere': because the sun and moon shine upon the whole world, when he eclipses them, his name is heard throughout the world).
