Thaandavam is a type of dance that originated in India a very long time ago. It's a very energetic and powerful dance where the person dancing moves their body in a way that expresses strong emotions like happiness, anger or love.
When a person performs Thaandavam, it's like they are telling a story with their body movements. They use their arms, legs, and torso to convey different emotions and symbols.
It's like when a person is happy, they might dance around and jump up and down. When they're angry, they might stomp their feet and make big movements with their hands. Similarly, the person doing Thaandavam will use different dance moves to show different emotions.
Thaandavam is usually done by men, and it requires a lot of skill and practice to be able to do it well. People who watch it are usually impressed by the dancer's energy and the way they move their body so gracefully.
