The Shiva Purana recounts the story of Mahadeva's encounter with the powerful asura (demon) Andhaka. Andhaka, born from the sweat of the asura Tarakasura, was gifted with a boon that made him invincible. Andhaka began to terrorize the gods and goddesses, who sought the help of Mahadeva. Mahadeva engaged in a fierce battle with Andhaka, but the asura seemed unbeatable. Just when it seemed that Andhaka would emerge victorious, Mahadeva created a powerful illusion, which made Andhaka realize that he was fighting his own shadow. Andhaka, confused and weakened, was ultimately killed by Mahadeva.
