What makes Mahakaleshwar different from the other 11 Jyotirlingas?

Mahakaleshwar is uniquely distinguished by three characteristics: it is Swayambhu (self-manifest, not consecrated by human hands), it is the only Dakshinamukhi (south-facing) Jyotirlinga among the twelve, and it is also considered one of the 18 Maha Shakti Peethas — giving it dual sanctity in both Shaiva and Shakta traditions.
