when he sensed a farishta at the edge of his field of vision. As he had done countless times before, he turned his head slowly, expecting the vision to vanish.
Instead he saw a dark shadow standing in front of the long bookcase. It was vaguely human-shaped. It turned slowly, revealing itself to be thin as paper—but as it turned it seemed to acquire thickness, hints of features over its dark, slender form. And then it seemed to Abdul that a door opened in the air, just a crack, and he had a vision of an unutterably strange world beyond. The shadow stood at the door, beckoning with one arm, but Abdul Karim sat still, frozen with wonder. Before he could rouse himself and get up, the door and the shadow both rotated swiftly and vanished, and he was left staring at the stack of books on the shelf.
After this he was convinced of his destiny. He dreamed obsessively of the strange world he had glimpsed; every time he sensed a farishta he turned his head slowly toward it—and every time it vanished. He told himself it was just a matter of time before one of them came, remained, and perhaps—wonder of wonders—took him to that other world.
Then his father died unexpectedly. That was the end of Abdul Karim’s career as a mathematician. He had to return home to take care of his mother, his two remaining sisters and a brother. The only thing he was qualified for was teaching. Ultimately he would find a job at the same municipal school from which he had graduated.
On the train home, he saw a woman. The train was stopped on a bridge. Below him was the sleepy curve of a small river, gold in the early morning light, mists rising faintly off it, and on the shore a woman with a clay water pot. She had taken a dip in the river—her pale, ragged sari clung wetly to her as she picked up the pot and set it on her hip and began to climb the bank. In the light of dawn she was luminous, an apparition in the mist, the curve of the pot against the curve of her hip. Their eyes met from a distance—he imagined what he thought she saw, the silent train, a young man with a sparse beard looking at her as though she was the first woman in the world. Her own eyes gazed at him fearlessly as though she were a goddess looking into his soul. For a moment there were no barriers between them, no boundaries of gender, religion, caste or class. Then she turned and vanished behind a stand of shisham trees.
He wasn’t sure if she had really been there in the half-light or whether he had conjured her up, but for a long time she represented something elemental to him. Sometimes he thought of her as Woman, sometimes as a river.
He got home in time for the funeral. His job kept him busy, and kept the moneylender from their door. With the stubborn optimism of the young, he kept hoping that one day his fortunes would change, that he would go back to college and complete his degree. In the meantime, he knew his mother wanted to find him a bride…
Abdul Karim got married, had children. Slowly, over the years of managing rowdy classrooms, tutoring students in the afternoons and saving, paisa by paisa, from his meager salary for his sisters’ weddings and other expenses, Abdul Karim lost touch with that youthful, fiery talent he had once had, and with it the ambition to scale the heights to which Ramanujan, Cantor and Riemann had climbed. Things came more slowly to him now. An intellect burdened by years of worry wears out. When his wife died and his children grew up and went away, his steadily decreasing needs finally caught up with his meager income, and he found for the first time that he could think about mathematics again. He no longer hoped to dazzle the world of mathematics with some new insight, such as a proof of Riemann’s hypothesis. Those dreams were gone. All he could hope for was to be illumined by the efforts of those who had gone before him, and to re-live, vicariously, the joys of insight. It was a cruel trick of Time, that when he had the leisure he had lost the ability, but that is no bar to true obsession. Now, in the autumn of his life
