Dasara saw large parts of India burning Ravan's effigies. But the death of Thotsakan, as the Thai call Ravan, is never celebrated.

In Thai culture representing death in any form is seen as bad omen and people there express surprise that Indians like to burn Ravan's effigies  reports Daily Yo.

The website also states that well-known Thai artist Somtow Papinian Sucharitkul, was forced to delete the scene of Thotsakan's death from his opera  "Ayodhya", in 2006, leading to a debate on the issue of freedom of expression.
Outside this, the similarity between Indian Ramayan and Thai epic Ramkien is striking.

Phra Rama, the son of King Tosarot of Ayothaya, is revered as an incarnation of Pra Narai. Thotsakan, a demon king  with ten heads and 20 arms, kidnaps Sida, leading to a huge war between demons and humans.
Ayutthaya, a city of Bangkok, was also the capital of Thailand for 400 years beginning the 14th century.

But in Thailand, Ramkien is more of a cultural heritage than a religious book.
