Rohinton Mistry is one of the most prominent writers of Post-Independence India. Though he left India and been as an immigrant writer his novels are true picture of India in its social, political and cultural sense. As a Parsi man, Mistry throws light on the sufferings of the marginalized people, down-trodden and the poor people of the society in his novels Such a Long Journey, A Fine Balance and Family Matters. His novels are the real record of the life styles, customs and traditions of the Parsis. Not only Mistry but also the writers like Bapsi Sidwa, Farrukh Dhondy and Ardashir Vakil had recorded all the cultural aspects of Parsis in their works. The culture in literature is crafted through the characters by the writers – the culture may be either writers own or the life of the characters. Writers in their works concentrate on many themes, but while detailing the theme of the culture, it is displayed in the way of age, period and people behavior. “Culture is the sum of all the forms of art, of love, and of thought, which in the course or centuries, have enabled man to be less enslaved”. This paper aims to emphasis the cultural identity of Parsi among the multicultural India through Mistry’s work Such a Long Journey. As a Parsi writer Mistry belongs to a religious and demographic minority within India. In Mistry’s novels we come to know the clear picture of Parsis suffering in India. He says that Parsi people suffer from double home sickness as they left their home
