The 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.
