Structure of Shri Nageshwar Jyotirlinga Temple
Nageshwar Mahadev Sivalingam is facing South while the Gomugam is facing east. There is a story for this position. A devotee by name Naamdev was singing bhajans in front of the Lord. Other devotees asked him to stand aside and not hide the Lord.
To this Naamdev asked them to suggest one direction in which the Lord does not exist, so that he can stand there. The enraged devotees carried him and left him on the southside.
To their astonishment, they found that the Linga was now facing South with the Gomugam facing east.
