This is the goddess Chamunda. She is depicted adorned by ornaments of bones, skulls, serpents and scorpions, symbols of disease and death. She stands over a headless corpse and there is a preta, which is a soul of the departed, on either side of her. One of these pretas is munching on a human hand. I find her image and surrounding images to be on the scary side. I would hate to meet her in one of my dreams.
