Nav means 'new' - it also denotes 'nine' the number to which sages have attached special significance since ancient times. Hence, we have Nav-ratri (9 nights), Nav-patrika (9 leaves / herbs / plants), Nav-graha (9 planets), and Nava-Durga (9 forms).
As per Hindu Mythology - Navdurga is the ultimate Shakti. It gives power, strength and stability to all life forms. The nine forms of Maa Durga is celebrated across India on a large scale during navratri. May Goddess Durga bestow all her blessings on all of us.
