涅槃經作「命命鳥」，勝天王般若經作「生生鳥」，阿彌陀經，雜寶藏經作「共命鳥」，梵名耆婆耆婆，一身兩頭之鳥也。玄應音義一曰：「梵言耆婆耆婆鳥，此言命命鳥，是也。」見共命鳥及耆婆耆婆條。
idem 命命鳥, also 耆婆耆婆 (耆婆耆婆迦); 闍婆耆婆 (闍婆耆婆迦) A bird of the partridge family; there is a fable about such a bird having two heads, called 迦嘍嗏 garuḍa, and 憂波迦嘍嗏upagaruḍa; one ate a delicious flower while the other was asleep; when the latter awoke, it was so annoyed at not sharing it that it ate a poisonous flower and the bird died; thus there is a Jekyll and Hyde in every one.
