The Jagannath Sanskruti has its roots in the ancient Odia literature and tradition. The cult of Jagannath is believed to have originated in the 12th century AD, during the reign of King Ananta Padmanabha of the Ganga dynasty. Over time, the sanskruti (culture) surrounding Lord Jagannath evolved, incorporating various tribal and local traditions. The Odia book PDF, "Jagannath Sanskruti," provides valuable insights into the historical and cultural context of this phenomenon.
