The myth of Kritimukha originates in ancient Hindu scriptures, especially the Shiva Purana. In mythology, a demon named Rahu, who was extremely powerful, had created a giant creature to kill Lord Shiva. But when the creature came face to face with Shiva, it immediately prostrated before the divine power. Impressed by the humility of the creature, Lord Shiva instructed it to eat its own body as penance. The beast complied willingly, leaving behind only its face. This face was then blessed and renamed Kritimukha by Shiva, representing total surrender, defense, and self-cleansing.
The Kritimukha face is generally shown with wide, staring eyes, flared nostrils, bared fangs, and a fierce expression—inspiring awe and reverence. Though horrific, it does not represent fear but fierce protection and spiritual transformation.
