Achala, defender of the faith, wears a tiger skin as a loin cloth and snakes as anklets and bracelets. He often stands over Ganesha/Ganapati (some say a deity with an elephant head called Vignayaraja) but here he is also trampling upon another deity, possibly Maheshvara. The shape of the double lotus base is typical of the 12th-13th century. He is holding a sword in one hand and a lasso in the other.
Here Achala has a sitting buddha in his flaming hair and unusual armbands and necklace. From the 13th century onwards, the petals of the lotus base are flatter and more elongated.
