Sanskrit the power of terror
A name most often used to indicate the "dark" and "terrible" aspect of the goddess who is the force of aging, the silent but ever present decay and destruction of all that lives. For fear of this "demonic force" who represents the inevitability of death, people have never built a single temple to her!
However, it is also said that the infinite variety of beings and forms in this universe is due to Bhairavi, which makes her less sinister and shows something of her creative side.
Sometimes, Bhairavi is said to be the dark side of Parvati, at other times she is identified with Kali. In the Kalika Purana, she is simply regarded as one of the many yoginis.
Note:
Bhairava is another name for the god Shiva.
