Machig Labdron lived around 1055-1149. She became a teacher (lama) and is traditionally represented like a wisdom dakini, with one head with 3 eyes, 2 hands, holding a vajra-handle bell and a drum, and 2 legs, in a dancing posture. She is adorned with a skull crown and bone jewellery.
Here she has a staff or khatvanga over her left shoulder and a garland of fifty freshly severed heads. The blackening of the face is due to fire damage.
