Alongside their Buddhist beliefs, for instance, many Thais worship Hindu deities, such as Brahma at the famous Erawan Shrine in Bangkok, and Ganesha, Indra and Shiva in countless places across the country. Numerous reliefs on temple walls, such as at PrasatHinPhima in Korat, describe the episode of Khrishna hunting wild boars. Furthermore, the popular Thai epic Ramkien is based on the Ramayana, which has widely inspired art, dance and literature. As the Thai Royal emblem depicts Garuda, the vahana of Vishnu, the royal household is no exception to this continuation of Hindu traditions and indeed BrahmLuang (Royal Brahmins) are often engaged to lead funerals, weddings and state ceremonies, such as the Royal Ploughing Ceremony to ensure a bountiful harvest. The Hindic roots of Thai culture are evident at the temple of Devasathan, which was established in 1784 by in the PraNakhon district of Bangkok by King Rama I in 1784 and became the centre of Brahminism in Thailand.
