Jwalathoranam (Jwala Thoranotsavam) is a ritual observed on Kartika Purnima. In 2019, Jwalathoranam date is November 12.
It is mainly celebrated in Lord Shiva Temples across Andhra Pradesh, Telangana and some parts of Karnataka. Two big wooden logs are erected and another log is placed upon them horizontally as a ‘Thoran’.
The horizontally placed log is tied with huge dry grass mass. The grass is lit with fire at the beginning of Jwalathoranotsavam. The grass lights like a big deepam. The processional deities of Lord Shiva and Parvati are taken up in a procession under the Jwalathoranam. This utsavam is called Jwalathoranotsavam.
The origin of Jwala Thoranotsavam is associated with the story of Ksheera sagara madhanam (churning of the Ocean).
Jwala Thoranotsavam is known as Karthigai Deepam (Mahadeepam) in Thiruvannamalai Arunachaleshwara Swamy Temple and other Shiva temples in Tamil Nadu.
