Avdhut
Once Lord Bhraspati and Indra were going to meet Lord Shiva. Indra was full of himself and with this thought in mind he was walking with a haughty air. Eventually they met a dishevelled man who was walking towards them.Indra asked the man to tell Lord Shiva that he and Brihaspati wanted to meet him. The man which was infact the Avdhut form of Shiva who wanted to break Indra's haughty nature.
When Avdhut refused to let them meet Shiva Indra got angry. He took out his Vajra to attack the man but his hand got frozen at that time. Brihaspati realised that this was Lord Shiva and fell down to his knees to apologise. Indra also understood his mistake and bent down to ask forgiveness.
