This Jyotirlinga is situated by the banks of Narmada river in the Malva area. Gods of all the Gods Lord Shiva's Omkareshwar linga is situated on the mountain Mandhata. The Shiv Purana speaks of the greatness of Omkareshwar and Mammaleshwar. The 2 sons of the sun dynasty Mandhata (Ambarish and Mucchkund), practiced severe penance and austerities here pleased Lord Shiva. They had also performed great religious sacrifices here, because of this the mountain is named Mandhata.

Before entering the temple one has to pass through 2 rooms. The Omkareshwar is not affixed to the ground, but is naturally installed there. There is always water around it. The significance of this linga is that the linga is not situated below the cupola. The idol of Lord Shiva is situated on the top of the temple. A huge fair is organised here on the day of Kartik Poornima.

Amongst the 12 Jyotirlingas Omkareshwar is undoubtedly considered but another name which often comes in this context is Mammaleshwar. Not only the name but the existence of these two are also thoroughly different. The temple of Maleshwar is situated south of the river Narmada, but both the forms of Shiva have been counted as one.

It is said that once upon a time Vidhya Parvat practiced severe penances and worshipped Parthivarchana along with Lord Omkareshwar for nearly six months. As a result Lord Shiva was pleased and blessed him with the desire boon. On the sincere request of all the gods and the sages Lord Shiva made two parts of the lings. In one he resided as the Pranav or Omkar and assumed the form of Omkareshwar and Bhagwan Sadashiva, Parameshwar, Amareshwar or Amaleshwar assumed form from the Partivlinga.
