Dakinis are female spiritual beings with great spiritual powers. They can be further divided in two main categories: the enlightened ones and the mundane ones.
The first group is constituted by very learned entities, equal to the bodhisattvas, manifesting themselves in the pure female forms. Usually they are the spiritual consorts of male deities and often the divine couples are depicted during the mystical and physical union.
The second group is formed by female spirits with different spiritual powers and diverse degrees of self-realization. Some of them are protective spirits of sacred objects (i.e. sacred books, relics, etc.), while others are wrathful nature spirits.
Tibetan: mkha'-'gro-ma (khandro).
