Damchen Dorje Legpa, 'the oath-bound Excellent Vajra' (Sanskrit Vajrasādhu), is among the best known of the indigenous Tibetan deities converted to Buddhism. Tradition holds that Padmasambhava subdued him in the eighth century and bound him under oath to protect the doctrine. He is depicted as a red, wrathful figure in the dress of a layman, wearing a round wide-brimmed hat and riding a brown billy-goat (or in other forms a snow lion), holding a vajra, a smith's hammer or a heart. He is the patron deity of Tibetan blacksmiths, a craft-association that links him with fire and the forge, and in the Nyingma school he serves, with Ekajati and Rahula, as one of the three special protectors of the Dzogchen (Great Perfection) teachings.
