The writings of Arun Joshi explore a variety of topics, such as the notions of nihilism & materialism, along with the concepts of quest & complacency. Other topics that are explored include alienation and engagement, compromise and east-west encounter, and nihilism and materialism. The extreme mental agony that his lonely travels went through is strongly depicted in the works of literature that he has created. The individuals in question are animals that are entirely bewildered and are always looking for the reason for their presence on Earth as well as their origins. After doing an analysis of Arun Joshi's work, The Foreigner, it becomes evident that crisis and longing are the key topics that are explored in his writing. In her work The Foreigner, Sindi Oberoi clearly depicts the suffering that she goes through as a result of her profound solitude and what she refers to as "rootlessness." This occurs when she moves from a state of detachment to one of active interaction with the world. In spite of the fact that Sindi was born into an unorthodox environment, he is making an effort to isolate himself. In spite of the fact that he is involved with other women, June forces him to confront his hypocrisy, cowardice, arrogance, and foolishness. The passing of June and Babu serves as a turning point in the narrative, while also increasing his sense of estrangement from the world. As part of his efforts to learn more about himself, he decides to travel to India (India). Although Sindi endures adversity on his path to enlightenment, he finally achieves a rejuvenated and purified spirit as a result of his perseverance. During this time, he comes to a profound realisation on the reason he is here on Earth. As a result of his understanding, he is able to appreciate that detachment does not include giving up one's own interests, but rather participating in deeds that are unselfish, as demonstrated in The Gita. This is the true essence of the notion of detachment. Essentially, the book is a severe condemnation of Sindi's estrangement and his flawed understanding of the process of generating distance between himself and others.
