This present research paper aims to explore the existential reflections present in Geetanjali Shree's novel, "Tomb of Sand." The novel delves into the profound themes of existence, identity, mortality, and the human condition. Through a meticulous analysis of the characters, plot, and literary techniques employed by the author, this paper sheds light on the existentialist undertones of the novel. By examining the characters' search for meaning, their struggles with isolation, and their contemplation of life's transient nature, this study uncovers the existentialist philosophy that permeates Shree's work.
