This painting by artist Panchugopal Dutta depicts Devi Durga's Aagman (arrival) and Gaman (departure):
It is a popular belief that Devi arrives and departs in some form of transportation which predicts the lives of people for the coming year. There are various forms like Nouka (Boat), Ashwa(Horse), Gaj (Elephant),Palki etc. each having its own significance. For eample coming by boat signifies natural gifts like a good harvest. On years when the Goddess arrives on an elephant, it is considered to be conducive to prosperity,it is believed that it brings plenty of rainfall for bumper harvesting in coming year.it is denoted to be the most peaceful mode.If the goddess arrives on boat,the departure by horse signifies devastation as was the case in early day's after any war.The week day, on which Navratri or Devi Paksha starts, is considered for Durga Arrival . If Goddess Durga arrives on Tuesday or Saturday ,it is believed that she comes mounting on a horse(Turang). Goddess Durga coming on a horse is not considered very auspicious. It is believed that it is omen of likely war among nations.Arrival on a palki (palanquin) spells widespread epidemic..and the boat suggests flood and misery. Durga Puja commemorates the annual visit of the Goddess with her children to her parents' home, leaving finally on the Dashami to be re-united with Shiva. This leaving ceremony is symbolised by the immersion of the sculptures on Dashami.Durga Puja is also a festivity of Good (Ma Durga) winning over the evil (Mahishasur the demon). It is a worship of power of Good which always wins over the bad..
