大般涅槃經義記 6.252

6.252

初中，「大醫名曰耆婆」標舉勸人。耆婆胡語，此云長命。初生之日棄之巷首而得不死，故號長命。其人善醫，故稱大醫。「往至王所白言安否」，試察王心，無愧則安、有愧不安。不安可救，故須試問。為成世王治病之行，故醫問之。

In the first [division], "The great physician named Jīvaka" names and introduces the person who advises. "Jīvaka" is a western language; here it means "Long Life." On the day he was born, he was abandoned at the head of a lane and yet did not die; hence he was called "Long Life." This person was skilled in medicine, hence he was called "great physician." "He went to the king's place and said, 'Are you well?'" tests and examines the king's mind: if he had no shame, he would be at peace; having shame, he would not be at peace. Being not at peace, he could be saved, hence [Jīvaka] needed to test and ask him. To accomplish the king of the world's practice of curing illness, the physician therefore questioned him.
