The most significant Hindu festival, Sharadiya Navratri 2021 will begin from October 7 and will culminate on October 15 withy Dussehra. Thursday marks the first day of the nine-day festival, 'Navratri' which is a celebration of the mighty valour of Goddess and all her different avatars. The festival defines Goddess Durga's victory as she defeated the demon Mahishasur. For these nine days people worship 9 avatars of Goddess Durga while following their fast. Each day of the Sharad Navratri holds great significance and considered as sacred.
Nava, that also means 'new', denotes 'nine' the number to which sages attach special significance. Hence, we have Nava-ratri (9 nights), Nava-patrika (9 leaves / herbs / plants), Nava-graha (9 planets), and Nava-Durga (9 appellations). Each goddess has a different form and a special significance.
