"The Northwest has always had a negative connotation in the Vedic tradition. Thus, R. Siddhantashastree writes: “The valley of the five tributaries of the Indus had always been held as an unholy region because of its occupation by a non-Aryan tribe antagonistic to the civilized Aryans until the time of Sambarana, (...) the king of Hastinapura belonging to the Lunar dynasty. He was the first Aryan to settle in the valley after driving away the aboriginal non-Aryans to a considerable distance.”"
