In Assam, Bengal and Odisha, Dol Purnima or Dol Jatra ; is a major festival. This festival is dedicated to Sri Krishna. On this auspicious day, an image of Krishna, richly adorned and besmeared with colored powder (Abir in Bengali and assam and Odisha), is taken out in procession, in a swinging palanquin, decorated with flowers, leaves, colored clothes and papers. The procession proceeds forward to the accompaniment of music, blaring of conch shells, trumpets and shouts of ‘Joi’ (victory) and ‘Hari Bol’ in odisha.
Dol Purnima becomes all the more significant for Bengalis, because this is also the birthday of Chaitanya Mahaprabhu (1485–1533). He was a great Vaishnava saint, who popularized modern sankirtana. He elevated the passion of Radha and Krishna to a high spiritual plane. He underlined the emotional at the cost of the ceremonial side of devotion. Followers of Chaitanya School of Vaishnavism, believe Chaitanya to be the manifestation of Krishna. Chaitanya Mahaprabhu believed that the essence of sadhana is always the loving remembrance of Hari.
