Blue Achala (who has a blue body on paintings) is the most common form of Achala sculptures. He may be kneeling or standing and he has a sword in his right hand and a noose in the other, with his fingers doing the karana mudra (to ward off evil).
He often stands on Ganapati.
The above has a square face with the standard three eyes and bared fangs that bite his lower lip. His hair is fastened to form a mitre-like shape. His five-leaf crown is decorated with flowing ribbons and semi-precious stones.
Achala sometimes raises his left index to do the lion gesture or tarjani mudra.
On this rare work, the crown panels are made of buddhas and there is a small buddha on top of his mitre-like chignon,
plus another at the back, likely to be the five dyani buddhas.
