AN actor who has ruled the stage for decades is in his twilight years. He is losing his eyesight, and is preparing for his final three performances. But in this play within a play, there is another layer of emotions at work — those shared between Satyasheel, the ageing thespian, and his son and actor Paritosh, who has grown up grappling with the void created by an absent parent. The estranged father and son portray Eklavya’s ghost and Abhimanyu respectively, but that’s not where the reference to the Mahabharata ends. For, throughout the production, the moonlit night when Krishna delivers his sermon to Arjuna is used as the central trope. That’s the premise of Abhishek Majumdar’s Kaumudi (moonlight), a play that opened in 2014 and is Bengaluru-based Bhasha Centre’s longest-running production.
