拘尸（舊經中或作拘夷那竭又作究拖那城者以梵言那伽𡆆此云城也譯言上茅城者多有好茅故也）。

拘尸 [Kuśi-] (in older sūtras, it was sometimes written as 拘夷那竭 [Kuśinagara], or as the city of 究拖那, because in the Sanskrit language nagara means city in our language. When translated as "City of Superior Grass," it is because there was an abundance of fine Kuśa grass there).
