Hi Usha, Navratri greetings to you and all the members of boddunan. In Maharashtra, we have Ghat Sthapana in our homes which basically celebrates the nurturing and sustaining nature of the the feminine power of Mother Earth and the Godesses Durga, Kali, Amba, parvati, Saraswati, Mahalaxmi etc. all of whom are manifestations of this divine, feminine power. Ghat is basically nothing but an earthern pot which is placed over a basket filled with earth in which seeds of nine grains are planted. The water from ghat permeates the soil and in nine days the grain grows into healthy saplings. It is a kind of tribute to earth that produces food and sustains us. On tenth day, the saplings are offered to god. It is a belief of the farmers that the healthier the saplings are, the better the rabi crops will be.

Kalyani, here in Karnataka too they have this custom, not in Mangalore though..In north Karnataka they arrange dolls with the statues of Goddesses and also have a tray or matki filled with saplings kept along with it.

In Gujarat, Navratri is celebrated with great fervour and Garbas and Dandiya Ras are performed to beautiful music beats. Girls are dressed in colorful lehnga choli and spectators throng to these venues in large numbers. TheGarbas of Vadodara are especially famous. however there are no holidays in educational institutes which looks a biy odd as it is the young who dance late into the night.
Here in mangalore we have a sizeable Gujarat community mostly into business, who have been living here since many decades and they organise Dandia and Garba dancing , which I too attend. It is a lot of fun and ladies of all ages and sizes , not just Gujaratis and the youngsters have a blast for 9 days ..
