Vajrayoginī (Sanskrit: Vajrayoginī वज्रयोगिनी; Tibetan: རྡོ་རྗེ་རྣལ་འབྱོར་མ་, Wylie: rdo rje rnal ’byor ma, Dorjé Naljorma) is an important figure in Buddhism, especially revered in Tibetan Buddhism. In Vajrayana she is considered a female Buddha and a ḍākiṇī. Vajrayoginī is often described with the epithet sarvabuddhaḍākiṇī, meaning "the ḍākiṇī [who is the Essence] of all Buddhas". She is an Anuttarayoga Tantra meditational deity (iṣṭadevatā) and her practice includes methods for preventing ordinary death, intermediate state (bardo) and rebirth (samsara) by transforming them into paths to enlightenment, and for transforming all mundane daily experiences into higher spiritual paths.
The origins of Vajrayoginī teachings date from between the 10th and 12th centuries, and draw inspiration from Hindu Shaiva tantras. She appears as the consort of Padma Thotreng Tsal, and of Cakrasaṃvara, while in Vajrayoginī standalone practice, her inseparable consorts are represented by the khatvanga (staff) on her left shoulder. The lineage of Vajrayoginī practice can be traced back to the original teachings of Vajradhara and is divided into three main lineages: Narokhachö, Maitrikhachö, and Indrakhachö.
