Kertanagara according to the Wurara inscription
The Wurara inscription of 1211 Shaka (1289 AD) mentions the title Jina Raja Kertanagara. This describes Kertanagara as a great and wise ruler. He knew the content of all the holy Buddhist books better than a priest, and he also preached the dharma.
After he was ordained, Kertanagara was given the title Jnanashivabajra, and to mark this event a statue was erected in the Wurara cemetery. This was the ancient domicile of Bharada, the Buddhist monk who, according to the inscription, was involved in the ritual division of the kingdom that took place at the end of Airlangga’s reign.
The Wurara inscription is carved on the pedestal of a Buddhist statue which has the bald head of a monk and its right hand in the earth touching gesture as is characteristic of the Buddha Akshobhya. This statue is commonly known as Joko Dolog. It is now in Taman Apsari, Surabaya.
