Significance of Kartika Purnima in Odisha

In Odisha, on Kartik Purnima, people celebrate Boita Bandana(Odia: ବୋଇତ ବନ୍ଦାଣ) by heading for the nearest water body to set afloat miniature boats, originally made out of banana stem and coconut stick, lit with Deepak(lamps), fabric, betel leaves. Boita stands for boat or ship. The festival is a mass commemoration of the state's glorious maritime history when it was known as Kalinga and tradesmen and mariners known as sadhabas traveled on boitas to trade with distant island nations that share borders with the Bay of Bengal like Indonesia, Java, Sumatra and Bali.

Odisha's past was glorious. Kalinga had a major influence in the maritime trade, At one time Myanmar, the Indonesian archipelago, and the Malay Peninsula were also called by the name of Kalinga. The founders of the Champa (Vietnam), Funan (Cambodia) and Shailendra (Indonesia) kingdoms were from Kalinga. Reference-Suvarnadvipa: Ancient Indian Colonies In The Far East (2 Vols.), Book by R. C.
