This remarkable hermit-saint, the Tibetan consort of Padmasambhava, is sometimes shown in Nirmanakaya form - the 'emanation body' a Buddha takes so as to be visible to ordinary beings - as a woman in everyday Tibetan clothes, seated and holding curved knife and skullcup.
She is also shown in deified form as the Queen of Great Bliss (Tib., Dechen Gyalmo) as a red standing figure with a damaru (double-sided drum) raised in her right hand and a curved knife held to the ground with her left.
