續高僧傳 2.8

2.8

Jñānagupta—rendered in the Sui language as Dezhi (Virtue-Resolve)—was from North Xiandou. "Xiandou" was originally pronounced Indravardhana, which means "place of the Lord," referring to its protection by the Lord of the Devas (Indra). The pronunciation "Xiandou" is merely an erroneous abbreviation in that land. "Shendu" and "Tianzhu" are erroneous appellations used here [in China]. People of that land simply call it "Xiandou" as a collective term, and then divide it into five regions.
