In Hindu mythology, the Brahmastra (IAST: Brahmāstra) is an astra (weapon) that is said to be able to destroy the whole universe, capable of destroying creation and vanquishing all beings. Only Parasurama, Rama, Meghnada, Bhisma, Drona, Karna, Ashwatthama, and Arjuna possessed the knowledge to invoke this weapon. It is one of the most destructive, powerful, and irresistible weapons mentioned in Hinduism. It was created by Lord Brahma along with its more powerful variants Brahmashirā astra, Brahmanda astra and Bhargavastra. It is termed as a fiery weapon that creates a fierce fireball, blazing up with terrible flames and countless horrendous thunder flashes. When discharged, all nature including trees, oceans, and animals tremble, and the sky surrounds with flame, glaciers melt and mountains shatter with copious noise all around. When used, the Brahmastra which is person-centric can destroy a powerful enemy if he does not possess an alternate counter weapon. If it is Brahmashirā astra, it causes collateral damage to every useful resource in a given area and prevents even a single blade of grass from ever growing in that area again. It is mentioned in Epic that there will be no rainfall for 12 Brahma years (12 Brahma years = 37.32 trillion human years) and climate conditions will worsen. The strike of the Brahmashirā astra will eventually destroy everything. When Ashwatthama hurled the Brahmashirā astra against Arjuna, the Pandava countered by invoking the same weapon; to prevent widespread destruction Narada and Vyasa stood between the two astras, ordering the two warriors to withdraw their weapons. (Arjuna, out of nobility, did so; Ashwatthama, however, out of anger refused to recall the astra and rather directed it to Uttarā's womb to kill the unborn Parikshita in an attempt to produce some level of damage to his opponents but Krishna intervened and saved the child and Ashwatthama was made to surrender the gem on his forehead and cursed by Krishna for 3000 years that he will roam in the forests with blood and puss oozing out of his injuries and cry for death but death would not meet him.) The origin of the word comes from the word Brahma, who is the "Creator" in Hindu culture. The idea that Brahmastra is the most powerful weapon can be understood by the kind of weapons that were used according to Hindu culture.
