Mudiyettu is a ritual dance drama from Kerala based on the mythological tale of a battle between the goddess Kali and the demon Darika. It is a community ritual in which the entire village participates. After the summer crops have been harvested, the villagers reach the temple in the early morning on an appointed day. Mudiyettu performers purify themselves through fasting and prayer, then draw a huge image of goddess Kali, called as kalam, on the temple floor with coloured powders, wherein the spirit of the goddess is invoked.
