Mahakaleshwar Avanti Ujjain

Even though the idol of Dakshinamurthy is installed in every Shiva temple, there are only a few temples where Dakshinamurthy is the chief deity. Only one of the twelve Jyotirlingas is Dakshinmurthy, The Mahakaleshwar in Ujjain. Being the only Dakshinmurthy Jyotirlinga, It holds special importance for Shaivites as a site of learning.
