The world grieved her loss and one mourner noted, "It was Mother herself who poor people respected. When they bury her, we will have lost something that cannot be replaced."

In appearance Mother Teresa was both tiny (only about five feet tall) and energetic. In old age, her face was quite wrinkled, but her dark eyes commanded attention, radiating an energy and intelligence that shone without expressing nervousness or impatience. Many of her recruits came from people attracted by her own aura of sanctity, and she seemed little changed by the worldwide attention she received. Conservatives within the Catholic Church sometimes used her as a symbol of traditional religious values that they felt lacking in their churches. By popular consensus she was a saint for the times, and a spate of almost adoring books and articles started to canonize her in the 1980s and well into the 1990s. She herself tried to deflect all attention away from what she did to either the works of her group or to the god who was her inspiration. She continued to combine energetic administrative activities with a demanding life of prayer, and if she accepted opportunities to publicize her work they had little of the cult of personality about them. In the wake of the 1979 Nobel Prize for Peace she received many other international honors, but she sometimes disconcerted humanitarian groups by expressing her horror at abortion or her own preference for prayer rather than politics. When asked what would happen to her group and work after her death, she told people that God would surely provide a successor—a person humbler and more faithful than she.
