Lord Kalabhairava is an intense form of Lord Shiva. Kalabhairava came from the Agni of Lord Siva Eye
Lord Kalabhairava will be on the tip of the trisul of Shiva & Adiparashakti. Kalabhairava takes trisul to any place by controlling the Kala (Time). Kalabhairava controls the kala and performs actions.
When Lord Shiva throws trisul up kalabhairava will take that trisul to the top of the sky in a fraction of a second and when trisul throws down kalabhairava will take thrisul to pathala lokam within a fraction of a second.
