One can see the sculptural representations of the ten incarnations of Vishnu (Dasha avatharas) on the front side of the idol. The figure of the river goddess, Ganga Mata can be seen at the feet of the deity, from which drops of holy water trickle at all times of the day.
The back portion of the idol, which displays the lovely female form of Jaganmohini and this figure, displays fine and flowing hair, perfectly combed and knit with flowers.
