Ravana considered to be the most revered and fierce devotee of Shiva, had many qualities that make him a learned scholar apart from being
called as the demon king. He was mastered in divine knowledge of six shastras and the four Vedas and hence known as Maha Pandit.

The depiction on this panel on one of the walls of the Virupaksha Temple is called Ravana Anugraha showing the ten headed Ravana lifting Mount Kailashvwith his twenty arms. According to the legends, when Ravana was once flying back to his abode after defeating brother Kubera,

his Pushpaka vimana was unable to fly over the Kailash mountain, Ravana got down and
met Nandi Shiva's mount who tells him that he cannot fly past MountvKailash, Shiva and Parvati's abode and disturb their dalliance.

Ego gets the better of Ravana who is in fact an ardent devotee of Shiva and he starts shaking Mount Kailash in an attempt to uproot it. This frightened Parvati Shiva then pressed on the mountain with his big toe of his foot trapping Ravana underneath mountain for thousand years.

Ravana then sings hymns of praise of Shiva all the years and gets a pardon from the Lord While all those years, Ravana let out blood curling screams
in agony and hence came to be known as Ravana The one who screams
