Kartika Purnima is important to the ancient history of Orissa. This recalls the maritime glory of the state. In ancient times the "Sadhabas" (Sea traders) used to sail to distant islands like Java, Sumatra, Borneo, Ceylon, etc., to trade for big boats ("Boita"). Women have been giving the community a warm send that same day. The days are gone, but the memory lives on. Now people float small boats made of cork and colored paper or bark of the banyan tree, while recalling the past glory. This is called "Boita Bandana".
