Vajrayogin? (Sanskrit: Vajrayogin?; Tibetan: Dorje Naljorma, Wylie: Rdo rje rnal ˇbyor ma; Mongolian: ????????? ?????, ????????, Chinese: 缝︽ダ Y?ji? k?ngx?ngm?) is the Vajra yogin?, literally 'the diamond female yogi'. She is a Highest Yoga Tantra Yidam (Skt. I??ha-deva), 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. Vajrayogin? is a generic female yidam and although she is sometimes visualized as simply Vajrayogin?, in a collection of her s?dhanas she is visualized in an alternate form in over two thirds of the practices. Her other forms include Vajrav?r?h? (Tibetan: Dorje Pakmo, Wylie: rdo-rje phag-mo; English: the Vajra Sow) and Krodikali (alt. Krodhakali, K?lik?, Krodhe?var?, Krishna Krodhini, Sanskrit; Tibetan: Troma Nagmo; Wylie: khros ma nag mo; English: 'the Wrathful Lady' or 'the Fierce Black One' ). Vajrayogin? is a ??ki?? and a Vajray?na Buddhist meditation deity. As such she is considered to be a female Buddha.
