16.2

「出愛王」者，即舊言優填王也。正本音言嗢陀演始（此云出）伐蹉（此云愛）褐剌闍（此云王）。優填，訛也。

'King Chual' (Out-of-Love King) is what was formerly called King Udayana. The correct original phonetic rendering is *udayan-si* (here meaning 'out'), *vatsa* (here meaning 'love'), *rājā* (here meaning 'king'). 'Udayana' [in the old translation] was corrupt.
