The term "Brahmāstra" refers to a powerful weapon in ancient Indian mythology, often associated with the epic texts like the Mahabharata and Ramayana. It is said to be a celestial weapon created by the god Brahma, capable of immense destruction. The weapon is often depicted as a last resort, used only in dire situations, and is said to be invoked through specific mantras. In the stories, the Brahmāstra can annihilate entire armies and landscapes, making it one of the most feared weapons. Its use is typically reserved for great warriors, such as Arjuna and Rama, who possess the knowledge and skill to wield it responsibly.
