Srutayudha was the then king of the present day Odisha, and he was mentioned in the great epic Mahabharata. He was the son of the ocean god Varuna and his wife Parnasa. Though he was supposed to live in the Varuna loka, but since he was interested to become a king in the earth, had ruled the Kalinga Kingdom, which is the present day Odisha.
Srutayudha was mentioned in the Mahabharata, as a young and charming person, who looks similar to his father Lord Varuna. He was well trained in war related activities, and he contained expert knowledge in all kinds of arts.Though he was told by his father Lord Varuna, to fight on the side of the Pandavas, due to his friendship with Duryodana, he fought on the side of Kauravas.
During the time of the Kurukshetra war, he has fought bravely. He was presented a powerful magical mace by his father Lord Varuna, but he is supposed to use it only on armed person. But while fighting in the Kurukshetra war, he attacked Lord Krishna with his mace, who is an unarmed person in the battle field, since he served as the charioteer of Arjuna. Due to that, his mace attacked himself, and killed him. After his death, he reached the abode of his father, the Varuna Loka, and it is believed that he is still living there by enjoying all sorts of pleasures in his life.
In certain incidents, we can find that the sons of the demigods were killed in the battle. But due to their supreme powers, similar to the phoenix bird, after their death, they would reach their original place. Abhimanyu, the brave son of Arjuna, had reached the abode of Lord Chandra, the Chandra Loka, since actually he is the son of Lord Chandra. Due to the special request of the demigods, Lord Chandra sent his son to the earth in order to serve the Pandavas, only for a period of 16 years.Though he was killed in the battle, his soul takes a new body, and entered into the Chandra Loka.
