Arun Joshi explores a variety of fictional topics, including existentialism, human misery and a lack of purpose, interactions between people of different cultures, and feelings of alienation. Each of the main characters in his stories, whether it be Som Bhaskar from The Last Labyrinth, Ratan Rathor from Apprentice, Billy from The Strange Case of Billy Biswas, Sindi Oberoi from The Foreigner, or Grand Master from The City and the River, goes through the process of dealing with the repercussions of their own identities. Every single one of the characters in his works is lost in the desert of self-exploration, trying to find their way through it. Even if they have a significant amount of riches, they do not have a sense of inner connection. Battles and wars have been fought by individuals throughout the course of human history in order to ensure that they would continue to maintain their existence. Because of his preoccupation with amassing wealth, he fails to recognise the significance of his own existence. The pursuit of his own self-interest and personal gain causes him to give up harmony, tranquilly, and happiness in his life. In a way that was both beautiful and profound, the well-known poet Thomas Grey explained that every path ultimately leads to death. Even if the events that take place in Arun Joshi's work might not have a direct influence on the characters, it is a universal experience that inevitably has an effect on each and every one of us at some point in our lives. As a result, this is an important worry that is present in all of Arun Joshi's literary works.
