Ravananugraha or Ravananugraha-murti (form showing favour to Ravana) is a benevolent aspect of the Hindu god Shiva, depicted seated on his abode Mount Kailash with his consort Parvati, while the rakshasa-king (demon-king) Ravana of Lanka tries to shake it. The depiction is labelled variously as Ravana Lifting Mount Kailash or Ravana Shaking Mount Kailash. According to Hindu scriptures, Ravana once tried to lift Mount Kailash, but Shiva pushed the mountain into place and trapped Ravana beneath it. For a thousand years, the imprisoned Ravana sang hymns in praise of Shiva, who finally blessed him and granted him an invincible sword and a powerful linga (Shiva's aniconic symbol, Atmalinga) to worship.
