Astra is a transcendental and supernatural weapon created by the gods and presided over by a specific Deity. To summon or use an Astra, one must have the necessary knowledge, that is, the specific mantra that will arm, direct and disarm Astra. In Mahabharata, Arjuna had more Astra than any other warrior. Arjuna had almost all Astra except Narayanastra.
the Mahabharata contains the story of a great battle fought between Pandavas and Kauravas. Within this sacred account, there are references to some highly advanced devastating weapons, of which the most severe may have been Brahmastra. The descriptions of these weapons clearly indicate an advanced science that possibly existed.
