Just as Part I begins with a chapter-long description of Chandrapore and its environs, Part II begins with a chapter-long description of the Marabar Hills and the caves.
Forster uses the phrase “nothing, nothing” twice in the opening chapter, and we see that the word “nothing” recurs numerous times throughout Part II. This focus on absence, or lack, combined with the menacing, primal setting of the Marabar Hills, sets an appropriate tone for Part II, in which the personal relations built up in Part I fall apart. In Part II, individual characters become isolated, confused, and sensitive to an eternal force just outside their comprehension—a force of nothingness and emptiness that is embodied in the Marabar Caves.
Aziz’s organized outing to the caves—the main event of these chapters and arguably of the novel as a whole—is fraught with misunderstandings and cruel ironies from the outset. A misunderstanding engenders the expedition to begin with: neither Aziz nor the women particularly want to go to the caves, but inaccurate currents of gossip convince Aziz that the ladies are eager to make the journey. Though Aziz plans the expedition meticulously, the entire affair is jeopardized, ironically, when Fielding—allegedly a stereotypically prompt Englishman—misses the train. Furthermore, though Adela and Mrs. Moore expect Aziz at least to provide them with an authentic view of India on the trip, they are disappointed to see that he has hired an elephant for them—a trademark of the inauthentic tours of India that the Turtons and other English colonials typically organize. Deepening the irony and misunderstanding, Aziz assumes that the women are delighted with the elephant, as he considers the animal a symbol of authentic India. Further irony comes from the fact that Aziz, who has never been to the Marabar Caves himself, is forced to act as the ladies’ tour guide, because the only person knowledgeable about the caves—Godbole—has been left behind.
To add to the aura of misfortune hanging over the expedition, both Mrs. Moore and Adela are plagued by a spiritual or emotional deadness that they date to the moment when Professor Godbole sings his Hindu song in Chapter VII.
