LiveIndia.com - Mahakal Jyotirlinga Shiva Temple.
One of the 12 Jyotirlingas in India, the lingam at the Mahakal is believed to be swayambhu (born of itself), deriving currents of power (Shakti) from within itself as against the other images and lingams which are ritually established and invested with mantra-shakti. The idol of Mahakaleshwar is known to be dakshinamurti, facing the South. This is a unique feature, upheld by tantric tradition to be found only in Mahakaleshwar among the 12 jyotirlingas. The idol of Omkareshwar Shiva is consecrated in the sanctum above the Mahakal shrine. The images of Ganesh, Parvati and Karttikeya are installed in the west, north and east of the sanctum sanctorum. http://www.liveindia.com/jyotirlinga/index.html
