Maa Bhairavi is the fifth Mahavidya of Maa Shakti. The name Bhairavi means "Terror" or "awe-inspiring" or "the fierce goddess". She is also called Tripura Bhairavi. "Tri" means three, "Pura" means fortress, castle, city, town, etc. Tripura Bhairavi conveys three different stages of consciousness i.e active, dream and deep sleep. She is in the form of all triads and once these triads are transcended, the Brahman is attained. In other words, once we have her grace, we can realize Shiva consciousness. Hence she is called Tripurabhairavi. The fifth Great Cosmic Wisdom of the Hindu pantheon is Tripura Bhairavi, correlated both to the terrible force of destruction of the evil and impure, and to the energy of the subtle universal fire.
The implications of these aspects are numerous. For instance, the purification action performed by the Great Cosmic Wisdom Tripura Bhairavi implies the manifestation of her savior aspect, because she saves her devotees from all suffering and negative karma-ic pressures.
