Why do people perform Garba during Navratri?

There are a lot of Hindus in India and some parts of the world that celebrate Navratri. One of their main traditions is to do the Garba. Garba is a type of dance that requires dancing around a symbol in order to show that all human beings have the sign of the Devi deep inside them.

Take note that this is danced in a ci1rcle and not in other shapes. Due to modern times, the sign of the Garba may be placed in the middle of the circle. By doing the dance, it can also be shown that even if the dancers will move in different directions, there is one thing that will remain constant which is the goddess that is placed in the middle.
