At sixteen, Tagore led his brother Jyotirindranath's adaptation of Molière's "Le Bourgeois Gentilhomme". At twenty he wrote his first drama-opera: "Valmiki Pratibha" ("The Genius of Valmiki"). In it the pandit Valmiki overcomes his sins, is blessed by Saraswati, and compiles the "Rāmāyana". Through it Tagore explores a wide range of dramatic styles and emotions, including usage of revamped "kirtans" and adaptation of traditional English and Irish folk melodies as drinking songs. Another play, written in 1912, "Dak Ghar" ("The Post Office"), describes the child Amal defying his stuffy and puerile confines by ultimately "fall asleep", hinting his physical death. A story with borderless appeal—gleaning rave reviews in Europe—"Dak Ghar" dealt with death as, in Tagore's words, "spiritual freedom" from "the world of hoarded wealth and certified creeds". In the Nazi-besieged Warsaw Ghetto, Polish doctor-educator Janusz Korczak had orphans in his care stage "The Post Office" in July 1942. In "The King of Children", biographer Betty Jean Lifton suspected that Korczak, agonising over whether one should determine when and how to die, was easing the children into accepting death. In mid-October, the Nazis sent them to Treblinka.
