問中，先敘問意。第二、正問。出愛王者，即舊言優填王也。正本音言嗢陀演那，此云出。伐蹉，此云愛。褐賴闍，此云王。優填者訛也。

In the inquiry, it first relates the intention of the question. Second is the inquiry itself. King Chuai ('Emerging-Love') is what was formerly called King Udayana. In the correct phonetic pronunciation it is called Udayana, which translates here as 'Emerging' (udaya); vatsa translates here as 'Love' (or calf); rājā translates here as 'King'. 'Youtian' (Udayana) was an error.
