Once Dadhichi and a king named Kshuva, a devotee of Vishnu, got into an argument over superiority of Kings over Brahmans and vice versa. Dadhichi punched Kshuva and Kshuva attacked Dadhichi with Thunderbolt. The injured sage was treated by Shukracharya. Dadhichi then did heavy penance to Lord Shiva who granted him three boons:- 1. He will never be Humiliated 2. He could never be killed 3. His bones will become as hard as a Diamond. Dadhichi returned to Kshuva and this time he defeated him. When Kshuva asked Lord Vishnu for help, the latter tried to trick Dadhichi. Dadhichi discovered the ruse, and attacked with the Trishula, upon which, all deities except for Lord Vishnu fled the scene.
