This son, Ganesha, is the most popular deity of the Hindu pantheon. The rat is Ganesha's vahana, but here, the harnessed rodent forms his throne. Ganesha sits on it in a posture of royal ease. The limbs of the stunted body are held together closely; the upper two hands holding his most popularly held attributes the ankusha and the pasa. His right hand is held in abhaya mudra and the other holds a modaka. His long trunk, unable to resist the sweet meat instantaneously turns left to partake it.
Numerous ornaments adorn his body but what catches instant attention is the serpent tried around Ganesha's waist. The serpent, as the tale goes, was responsible for tripping the mouse on which Ganesha was traveling and made him fall off, splitting his belly in the process, with the modakas spilling out. Ganesha put back the sweets and tied his belly with the serpent.
