Vajrayoginī (; , Dorjé Neljorma; , ) is the vajra . She is an Anuttarayoga Tantra iṣṭadevatā and her practice includes methods for preventing ordinary death, intermediate state ( bardo) and rebirth (by transforming them into paths to enlightenment), and for transforming all mundane daily experiences into higher spiritual paths.
Vajrayoginī is a generic female iṣṭadevatā and although she is sometimes visualized as simply Vajrayoginī, in a collection of her sādhanās she is visualized in an alternate form in over two thirds of the practices. Her other forms include Vajravārāhī ( "Vajra Sow") and Krodikali (alt. Krodhakali, Kālikā, Krodheśvarī, Krishna Krodhini, Tibetan Tröma Nakmo; , "Wrathful Lady", "Fierce Black One"). Vajrayoginī is a and a Vajrayana Buddhist iṣṭadevatā. As such, she is a female Buddha.
Vajrayoginī is often described with the epithet sarvabuddhaḍākiṇī, meaning "the who is the Essence of all Buddhas".
Vajrayogini's sādhanā originated in India between the tenth and twelfth centuries. It evolved from the , where Vajrayoginī appears as his Yab-Yum consort, to become a stand-alone practice of Anuttarayoga Tantra in its own right. The practice of Vajrayoginī belongs to the Mother Tantra class of Anuttarayoga Tantras along with other tantras such as the Cakrasaṃvara and Hevajra Tantras.
According to scholar Miranda Shaw, Vajrayoginī is "inarguably the supreme deity of the Tantric pantheon. No male Buddha, including her divine consort, Heruka-Cakrasaṃvara, approaches her in metaphysical or practical import."
