Time decides the importance of a writer. I believe in no ideology, but one should change with time. Even the literary movement should change from time to time. A writer is the mirror of society and he remains chained to society. When a writer feels the sorrows and sufferings of the society, he must express the feelings in his stories.
Many writers define the problems of the society in their stories, but that is just the beginning.
Merely defining problems is not the solution. For example, 'Annadata', a story by Kishan Chander, depicted the starvation of Bengal during the famine in which lakhs of people died. This story might have moved the readers at that time, but it is not an immortal story. Had the story depicted the death of one man, it would have been more heart rendering, compared to describing the death of lakhs of people. Recently, during the Kargil War, Abdul wandered amongst the dead bodies of Indian and Pakistani soldiers.
