On the left side of the door is the four-armed Blue Mahakala (called Chandamaharoshana by Tucci), holding a sword and a vajra-topped curved chopper in his right hand, and a khatvanga (a staff with three human skulls, topped with a trident) and skull cup in his left. He is pot-bellied and stands on a human corpse. Photo - Weyer/Aschoff: Tsaparang, Tibets Grosses Geheimnis,
