In Hindu mythology, Ravana is typically portrayed as a complex character, who is both revered and reviled. On the one hand, he is known as a great scholar and a master musician who possessed immense knowledge of the Vedas, the ancient Hindu scriptures. He is also believed to have been a devout devotee of Lord Shiva.
However, Ravana is primarily remembered for his role as the primary antagonist in the Hindu epic, the Ramayana. In the story, Ravana abducts Sita, the wife of Lord Rama, and takes her to his kingdom of Lanka. This leads to a long and brutal war between Lord Rama and Ravana, which ultimately ends with Rama defeating and killing Ravana.
As such, Ravana is often depicted as a villainous figure in popular culture, and his name is often used to represent evil and wrongdoing. However, in some parts of India, particularly in the southern states, Ravana is worshipped during the festival of Navaratri as a symbol of power and knowledge.
