Though Vaishnavism prevailed in Orissa much earlier, the cult of Krishna worship was made popular during the 15th century by Sri Chaitanya and his followers. Though temples exclusively dedicated to Krishna are few in Orissa, the representative deity of Lord Jagannath is no other than Krishna known as Madan Mohana, Ramakrishna, Gopala, Gopinatha etc.
To the Vaishnavas the festival is known as Jhulan Purnima or the Swing festival which is observed in most of the Vishnu temples and monasteries following the cult. Beginning from the Tenth day of the bright fort-night, it culminates on the Purnima day. The metal images of Radha and Krishna are placed on beautifully decorated swings and nights are spent with singing and dancing in front of the deities. As an important festival of Lord Jagannath, the celebration of the festival in the shrine and monasteries at Puri attracts visitors from far and near. The festival in the temple was first initiated by the Gajapati king Dibyasingha Dev-II (1793-1798).
