Nilachala, also renderedNiladri is a region corresponding[further explanation needed] toPuri, in the Indian state ofOdisha.[1][2]
According to theSkanda Purana, KingIndradyumna ofAvanti is said to have dreamt of the deityNilamadhava. The king is regarded to have dispatched many priests and messengers in the search of this elusive deity, regarded as a form ofVishnu. Finally, Vidyapati, one of the priests of Indradyumna, located theimage of Nilamadhava at Nilachala, at the sacred region of Purushottama Kshetra, and took the news back to the king. The image of the deity vanished before Indradyumna's arrival. After being propitiated,Vishnu is stated to have offered instructions for the construction of theJagannath temple of Puri, also in Nilachala.[3][4]
Indologist and Jagannath cult researcher,Heinrich von Stietencron in "The Advent of Vishnuism in Orissa: An Outline of its History According to Archaeological and Epigraphical Sources from the Gupta Period up to 1135 AD." in A. Eschmann et al., The Cult of Jagannath and the Regional Tradition of Orissa, Delhi: Manohar, pp. 1–30, hypothesizes the actual existence of a mountain at Puri in the past and said:
'No real mountain exists in the Puri town. Yet it is true that the Jagannath temple was actually built on a hill which receded sharply on its western side. Drifting sands and the sediments of continuous settlement have combined to raise the ground at the foot of the hill considerably so that the difference in level to the temple is no longer striking. It can be noticed, however, when approaching the ancient Siva temples which were situated to the west and to the north of the Hill.'[5]
Another hypothesis regarding the naming of Puri as 'Nilachala' has been advanced by the noted historian, Dr. Krushna Chandra Panigrahi, in his "History of Orissa", pp. 338–339. It has been argued that no mountain existed at the Jagannath shrine, and:
""Then the Bhaumas came fromAssam in the first part of the eighth century A.D., ruled overOrissa, obtained the shrine from theSavaras, got the temple built on the spot and gave it the nameNilachala, which was the name of the famous shrine ofKamakhya in their homeland ofAssam."."
