This is one of the many variants of Shri Devi (Palden Lhamo in Tibet) with one head and four arms. She holds two swords, a skull cup and a missing object.
The above holds the hide of an elephant, over a human skin, across her back with her upper hands. She has a flaying knife and a skull cup in her lower hands. She sits sideways on her dead son’s skin, which she uses as a saddle to ride her mule.
There is a crescent moon topped with a sun disc on top of chignon. Her five-skull crown is adorned with foliate panels and beaded festoons.
Accompanied by Makaravaktra, the small attendant standing near the plain oval base, this one holds a sword and a skull cup on one side, a (missing) trident and a spear on the other (which, in theory, corresponds to her Dudsolma form).
She has three bulging eyes and some protruding fangs. Her flaming hair and eyebrows are painted with orange pigment, her skull crown and jewellery are inlaid with hard stones. There is a garland of severed heads around her neck.
The texts that describe Palden Lhamo sometimes mention a mule (as on the first picture) and sometimes a wild donkey (as on the second picture, or so it seems…).
