Hinduism in Indonesia
Hinduism first came to the Archipelago during the 4th Century. The first Javanese Kingdom that we know of, Tarumanegara, was a Hindu Kingdom ruled by King Purnavarman. It was the Hinduism of the Lesser Vehicle - Hinayana - that first flourished here. The religion was also widespread on Sumatra. A Hindu sage mentioned by name is Cakyakirti who resided near contemporary Palembang.
The Hinduism that flourished in Indonesia elevated Lord Siva as the supreme being. In many cases he was identified with Agastya, the Supreme Teacher. Traditional Hindu iconography places a statue of Siva in the centre, flanked on the right by Agastya, and on the left by his consort Parvati. Ganesha, his son, stands behind him. It is likely that some form of supreme teacher or being was already revered in the Archipelago who then was identified with Siva as Hinduism was introduced. The similarity could even have helped the acceptance of Hinduism.
