Bhairava (Mahakala Bhairava) is a Hindu Tantric deity worshiped by Hindus. In Shaivism, he is a fierce manifestation of Rudra associated with annihilation. In Trika system Bhairava represents Supreme Reality, synonymous to Para Brahman. In Hinduism Bhairava is also called Dandapani (as he holds a rod or Danda to punish sinners) and Swaswa meaning "whose horse is a dog". In Vajrayana Buddhism, he is considered a fierce emanation of boddhisatva Manjusri and also called Heruka, Vajrabhairava and Yamantaka.
