Triyampawai ceremony
The Triyampawai Ceremony is a Hindu ritual currently celebrated at the Devasathan in Bangkok. It was formerly one of the twelve monthly royal ceremonies of the Thai court and is identified with the Tamil Thiruvempavai tradition.
History
It is believed that Thiruvembavai was introduced to Thailand by Tamils who immigrated to then Siam in 14th century CE. Available historical evidences confirm that the ritual of Thiruvembavai has been observed at Ayutthaya, Sukhothai, and Sawankhalok, the ancient capitals of Thailand. Initially it was observed as a penance and fasting at Sawankhalok and Phitsanulok, and later it got royal patronage and became one of the 12 royal ceremonies combined with the swing ceremony.Rituals
Triyamphway was celebrated to praise the Hindu god Siwa, who was believed to come visit Thailand at the end of every Thai year. He was offered with rice, fruits, and vegetables. Great Swing ceremony was celebrated to make him happy at the well known Sao Chingcha. So many Thai folklores interpret the connection between Siwa and Swing with interesting explanations. After ten days, it was believed that the companion of Siwa, Narai, visits and blesses Thailand for five days.Triyamphway mantra, actually Tamil Thiruvempavai stanzas of Saint Manikkavasagar, was recited in these days. The first 11 stanzas recited in front of Siwa are known as ""Pothmurai yay", while the other 9 stanzas recited in front of Narai are known as "Pothmurai clang". The two main deities of Shaivism and Vaishnavism are praised by single Thiruvembavai of Manikkavasagar, which is a saivite literature.
