[2] Another recorded source of Sanjaya's history and his successors is found in the Balitung charter and the Wanua Tengah III inscription.

The lingam is sited on the noble island of Yawadwipa (Java), which the inscription describes as blessed with an abundance of rice and gold.

Amid a period of confusion Sanjaya, son of Princess Sannaha (the sister of King Sanna) ascended to the throne.

By erecting a Shivaic lingam he demonstrates the establishment of the new authority, a new center of political power or court (kraton).

An analysis of the inscription, which was marked as a warning to vassal states and defeated kings, suggests that the Ukir Hill was the first center of the Mataram Kingdom.
