[164] "Whether I go or whether I do not go, I shall not thereby become immortal; having attended upon you in your happiness, how could I forsake you in your suffering (dukkhita)? Death together with you, or life without you — that very death is better than that I should live without you. It is not right (dhamma), great king, that I should forsake you who have come to such a pass; whatever destiny (gati) is yours, that same is pleasing to me, O lord of birds (vihagādhipa)."
