先陀婆（淨三藏云是石鹽也出在信度河邊故以河為名今經云一名四實此喻智臣相時而用）。

先陀婆 (saindhava: Tripiṭaka Master Yijing said that it is rock salt; it is produced along the banks of the Indus [Sindhu] River, hence it takes its name from the river. The present sūtra says: 'One name with four realities'; this is an analogy for a wise minister who acts according to the circumstances).
