Vajrayoginī (Sanskrit: Vajrayoginī वज्रयोगिनी; Tibetan: རྡོ་རྗེ་རྣལ་འབྱོར་མ་, Wylie: rdo rje rnal ’byor ma, Dorjé Neljorma; Mongolian: Огторгуйд Одогч, Нархажид, Chinese: 金剛瑜伽母; pinyin: Jīngāng Yújiāmǔ) is a Tantric Buddhist female Buddha and a ḍākiṇī. The Vajrayogini cult dates back to the tenth and twelfth centuries. Vajrayoginī's essence is "great passion" (maharaga), a transcendent passion that is free of selfishness and illusion—she intensely works for the well-being of others and for the destruction of ego clinging. She is seen as being ideally suited for people with strong passions, providing the way to transform those passions into enlightened virtues.
