Navratra is a very important and major festival in the western states of India: Gujarat, Maharashtra, and Karnataka during which the traditional dance of Gujarat called "Garba" is widely performed.
It is a folk dance, where people of different background and skills join and form concentric circles. The circles can grow or shrink, reaching sizes of hundreds, sometimes thousands of people, dancing and clapping in circular moves, in their traditional costumes, at the same time. The garba dance sometimes deploys dandiyas (sticks), coordinated movements and striking of sticks between the dancers, and teasing between the genders . Post dancing, the group and the audience socializes and feasts together.
Navratra in Gujarat is one of the state's main festivals. The traditional celebrations include fasting for a day, or partially each of the nine days such as by not eating grains or just taking liquid foods, in remembrance of one of nine aspects of Shakti Goddess. The prayers are dedicated to a symbolic clay pot called garbo, as a remembrance of the womb of the family and universe. The clay pot is lit, and this is believed to represent the one “Atman” (soul, self).
The period of nine days of Navratra is considered to be very holy for Hindus, People wake up and bathe early morning and pray to the Goddess. They perform special Pujas and Havans to welcome Goddess Durga to take shelter in their homes. Offerings in terms of delicious “Bhog” (food made for Goddess) fruits and flowers are also made to
the deity.Devotees also observe ritualistic fasts as a mark of showing their devotion for the Goddess.
People wish for a good life, healthy mind and body, and pray for spiritual, emotional and physical well-being. The Puja rituals are observed for nine days straight[ , with each day signifying the importance of one “Avatar” (incarnation) ofGoddess Durga.

Dances performed include Garba, especially in Gujarat.
