It concludes with Dushshera festival on the 10th day marking the victory of Lord Rama over Ravana the Lanka King. Navaratiri is celebrated all over India with a variety of prayers and fervour.
In TamilNadu, it is celebrated as Navaratri Golu. The idols of all the Gods and Godesses made of clay, papermace, cotton, wood, brass, etc, are displayed in steps. The steps are called golu padis. Golu padis are arranged in odd numbers like 3, 5,7,9 etc. The padi is covered with a cloth and dolls are arranged on them. Children participate with great interest in this arrangement and make themes of avatars of the Gods and His creation.
