Document 7: Karnabharam: Karnabharam or "The Anguish of Karna" (literally: "The Burden of Karna") is a Sanskrit one-act play written by the Indian dramatist Bhasa, an Indian playwright complimented even by the famous Kalidasa in the beginning of his play Malavikagnimitram . The play describes the mental pain of Karna on the previous day of the Kurukshetra War. Karnabharam is essentially the retelling of an episode of the Indian epic Mahabharata but the story is presented in a different perspective in the play. It is perhaps the only potential tragedy in the classic Sanskrit literature, presented in a form that comes closest to the "Vyayoga" (Sanskrit: व्यायोग) form of one-act play. That is so perhaps because the Natya Shastra ordains the playwrights to create plays for recreation, and essentially create happy endings . In Karnabharam, the tragedy does not occur on-stage (Unlike Urubhanga, a tragedy that shows Duryodhana dying - again, written by Bhasa). Karnabharam shows the valiant, generous, righteous Karna riding out towards the battle-ground, where his death under heart-wrenching circumstances is certain. The basic plot of this play is inspired by Mahabharata.
