Origin story
When Sati immolated herself at Daksha's yajna, Shiva tore a lock from his hair and created Veerabhadra, who destroyed the sacrifice and subdued the gods assembled there. He is worshipped as the protector of dharma and the punisher of arrogance.
Veerabhadra appears in the Puranas as the fierce form born of Shiva's wrath, accompanied by Bhadrakali. The sword, the bow and the fiery form express righteous anger and courage, and he is invoked against injustice and to guard the temple.
