astra

Astra is a term of Sanskrit origin meaning weapon or instrument. In ancient Indian epic literature, an astra is a supernatural, invocable weapon granted by divine power and described as being wielded by heroes after reciting a mantra and mastering the requisite discipline. Astras are contrasted with conventional weapons and require specific invocations to unleash their effects; improper use is said to bring consequences.

Examples include the Brahmastra, Pashupatastra, Agneyastra, Varunastra, and Nagastra. In Hindu myth, astras play a central role in action sequences; they are often depicted as devastating but limited by restraint or the need for accurate aim.

In modern usage, the concept has been appropriated as a proper noun in branding and industry. For example, Opel Astra is a line of compact cars produced by Opel and its Vauxhall division. Astra Space is a U.S.-based aerospace company developing small launch vehicles. The term is also used in various other product and corporate names, reflecting its mythic associations with power, technology, and precision.

Overall, astra retains its roots in ancient literature as potent, rule-bound weapons, while also serving as a versatile modern-name element for products and companies around the world.
