Which lion-faced dakini is a powerful protectress in Tibetan Buddhism?

Simhamukha is the lion-faced dakini regarded as a powerful protectress and obstacle-removing figure in Tibetan Buddhism.

Her name means “Lion-Faced,” and her Tibetan name, Senge Dongma, refers to her snow-lion head. She is generally portrayed as a fierce, often dark or blue dakini whose roar represents the force that disperses hostile influences, magical attacks, and confused or discursive thought.

Simhamukha is especially important in the Nyingma and Sakya traditions, which preserve distinct transmission lineages and ritual practices dedicated to her. In Nyingma treasure traditions, she may be understood as a manifestation of Padmasambhava in a secret, wrathful form used to remove spiritual obstacles and negativity. Other accounts connect her with Guhyajnana Dakini, Mandarava, or Sangwa Yeshe.

Her lion face distinguishes her from Vajravarahi, whose defining animal feature is a sow’s head. Palden Lhamo is another major Tibetan protectress, but she is usually shown as a wrathful goddess riding a mule, not as a lion-faced dakini. Simhamukha’s identity is therefore clear from the question’s animal-headed description.
