Summoning of Astra
To summon or use an astra required knowledge of a specific incantation/invocation, when armed. The deity invoked would then endow the weapon, making it impossible to counter through regular means.
Specific conditions existed involving the usage of astras, the violation of which could be fatal. Because of the power involved, the knowledge involving an astra was passed in the Guru-shishya tradition from a Guru (teacher) to a Shishya (pupil) by word of mouth alone, and only following the establishment of the student's character.
Certain astras had to be handed down from the deity involved directly, knowledge of the incantation being insufficient.
Astras in Hindu Epics
Astras come into importance mainly in the Ramayana and Mahabharata, where they are used in the great battles described in each epic. They are depicted as used by archers such as Sri Rama, Lakshman, Karna, Arjuna, Indrajit (Meghnad) the son of Ravana, and other warriors.
Lord Parashurama and Indrajit (Meghnad) the son of Ravana, are believed to be the only humans who ever possessed the three ultimate weapons of trinity.Parashurama was a disciple of Lord Shiva and learned the scriptures and the arts of warfare from Lord Shiva, then acquired Divya Astras from Lord Shiva and the other gods on Lord Shiva's instructions. At a very young age, Indrajit (Meghnada) became the possessor of several supreme celestial weapons, including Brahmanda astra, Pashupatastra and Vaishnavastra, under the guidance of Shukra, the Guru of the Daityas (demons). Shukra was a disciple of Lord Shiva.
|Lord Shiva's Teen Baan (three infallible arrows)||Shiva, The Destroyer||Lord Shiva gave Barbarika three infallible arrows (Teen Baan). A single arrow was enough to destroy all opponents in any war, and it would then return to Barbarika's quiver. The first arrow is used to mark all the things that Barbarika wants to destroy. On releasing the third arrow, it would destroy all the things that are marked and will then return to Barbarika's quiver. If Barbarika uses the second arrow, then the second arrow will mark all the things that Barbarika wants to save. On using the third arrow, it will destroy all the things that are not marked. In other words, with one arrow Barbarika can fix all his targets and with the other he can destroy them. Sri Krishna disguised as a Brahmin stopped Barbarika to examine his strength. When asked how many days he would take to finish the Kurukshetra War alone, Barbarika answered that he could finish it in one minute. Barbarika came to be known by the appellation Teen Baandhaari, the "Bearer of Three Arrows".|
