Varunastra

The Varunastra (Sanskrit वरुणास्त्र) is the water weapon (a storm) according to the Indian scriptures, incepted by Varuna. In stories it is said to assume any weapon's shape, just like water. As per the Indian legends or Puranas this weapon is said to have been obtained by great warrior characters such as Arjuna, Satyaki, Dhrishtadhuymna, Dronacharya, and many other illustrious warrior characters. The scriptures says this weapon was obtained by meditating on Varuna or Shiva, and was to be used with great care and skill. The usage of weapon was not possible for any inexperienced warrior, as a slight mistake committed, and the user himself could be destroyed. Indian scriptures and epics give large insights about weapons used by proper use of mantras. Weapons were used by chanting of mantras in the manner prescribed.
