3 – Keerat Avatar
It is said that lord Shiva took the form of Keerat or hunter while Arjuna was meditating. Duryodhan had sent a demon named Mooka to kill Arjuna. He heard the loud noise of the demon while meditating. He and Lord Shiva struck the boar at the same time and then Arjuna challenged Keerat, the avatar of Lord Shiva as who would strike the board first. Impressed by Arjuna Vellore, Lord Shiva gifted him his Pashupata.
