Olasuni hill stands on the border of Cuttack and Jajpur district, next to the Lalitgiri and Ratnagiri hills and the Gobari river. The famous saint Arakhita Das after travelling widely, finally chose Olasuni hill as his Sadhana Pitha. There he meditated in a cave for a long period and finally attained salvation. The hill is dotted with temples, among which the temple of Goddess Olasuni, the presiding deity and the tomb of Saint Arakhit Das are famous.
The sleepy Olasuni hill wakes up to the delight of the devotees, on Magha Ekadasi every year, who throng the place in large numbers to witness the nine-day Gumpha Yatra. The Yatra commemorates the death anniversary or Shradha Mahostav of the saint Arakhita Das who lived here 200 years ago. The saint, known as Balbhadra before taking up sanyas, was born in the Badakhemendi royal family of Ganjam. He renounced the world at the age of fifteen. He was named Arakhita by a widow who mistook him to be a thief. A non believer in idol worship, his spiritual writings include Mahimandala Geeta, Bhakti Tika, Saptanga Abadhuta Samhita and Tatwa Sara Geeta. After his death in 1833, his samadhi pitha became a sacred shrine.
His disciples follow the idealism of ‘Abadhuta bada’, where devotees irrespective of caste, creed and religion offer ‘Podapitha’ (a kind of cake), ‘Sukhua’ (dry fish) and ‘Somarasa’(wine) as samarpana Bhoga at the shrine for the fulfillment of their desire. ‘Kanjipani’, a kind of soup made from rice gruel, is the most popular Bhoga at the shrine. People come to the shrine to get a handful of the Kanjipani as they believe that it has some medicinal properties, which even can cure some incurable diseases.
