Aspects of Hinduism continue in Burma today, even in the majority Buddhist culture. For example, Thagyamin is worshipped whose origins are in the Hindu god Indra. Burmese literature has also been enriched by Hinduism, including the Burmese adaptation of the Ramayana, called Yama Zatdaw. Many Hindu gods are likewise worshipped by many Burmese people, such as Saraswati (known as Thuyathadi in Burmese), the goddess of knowledge, who is often worshipped before examinations; Shiva is called Paramizwa; Vishnu is called Withano, and others. Many of these ideas are part of thirty-seven Nat or deities found in Burmese culture.
