Indrastra (Sanskrit: इन्द्रास्त्र, romanized: Indrāstra) is the astra (celestial weapon) of the Hindu deity Indra.
One of these was King Sudakshina, who threw his spear at Arjuna, striking him and causing his blood to flow.
Even as the Kauravas believed him to be dead, Arjuna launched the Indrastra, killing King Sudakshina and a large part of his army.
[citation needed] On the seventeenth day of the war, Arjuna shot his Indrastra on the Samsaptakas, killing many of them.
[citation needed] In the Ramayana, Lakshmana employs the Indrastra to kill Indrajita, the son of Ravana.
