A river of western भारत . This river sits in the court of वरुण in the form of a nymph. [mh-2-1-9 ] Mahābhārata • Sabhā parva . श्रुतायुध , a valiant soldier who fought against अर्जुन in the great कुरुक्षेत्र battle was the son of पर्णासा . वरुण was the father of श्रुतायुध and at the time of the birth of a son for her she requested वरुण to grant her a boon that her son would not be killed by anybody. वरुण while granting her the boon gave the son a mace. That mace had a peculiarity. If the mace was used against anybody who was not fighting, the mace would turn back and kill the user. With the help of that mace श्रुतायुध gave अर्जुन a fierce fight and in the midst of the heat he forgot the condition stipulated by वरुण and used it against श्री कृष्ण who was standing nearby watching their fight. The mace turned back and killed श्रुतायुध . [mh-7-92-1 ] Mahābhārata • Droṇa parva .
