The fearsome manifestation of Shiva, grants devotees liberation from misery and suffering, showering divine blessings upon devotees.
Kalabhairava is a manifestation of Shiva associated with annihilation. The word points to a “terribly fearsome form." Kalabhairava is the protector of the Shaktipeethas (Shakti Peethas are sacred spots linked to the Goddess Shakti in Hinduism). (They mark where parts of the goddess fell, and people visit them for blessings.)
In the narrative, Kalabhairava's connection with the Shaktipeethas is rooted in the tragic event of Sati Devi's self-immolation at Dakshayagha. Following this sorrowful incident, Shiva, in his wrath, confronted Daksha, the one responsible for Sati's death, and eventually, Daksha met his demise.
In grief and anger, Shiva carried the lifeless body of Sati Devi and performed the Tandava, a divine dance of destruction. As Shiva danced, parts of Sati Devi's corpse fell to the earth at various locations, creating the Shaktipeethas. These sacred spots symbolize the divine energy of the goddess and are revered by devotees for their spiritual significance, and each such one is accompanied by a prathishtha of Kalabhairava. Kala Bhairava holds significant importance in Hinduism. Legend has it that he destroys fear and shields devotees from inner enemies like greed, anger, and lust.
There are several stories regarding the manifestation of this moorthy. Kala Bhairava was created by Shiva, beyond the constraints of time and death, to vanquish demons during the Devas versus Asuras war. Another legend says that Kala Bhairava was born due to the wrath of Lord Shiva when Brahma criticized him during a debate among the three major deities, Vishnu, Shiva, and Brahma. He is portrayed as the ultimate destroyer, wearing serpents and garlands made of skulls that produce substantial, terrifying sounds. Kalabhairava is found as Kshetrapala in different temples.
