'Call Within a Call' On September 10, 1946, Mother Teresa experienced a second calling, the "call within a call" that would forever transform her life. She was riding in a train from Calcutta to the Himalayan foothills for a retreat when she said Christ spoke to her and told her to abandon teaching to work in the slums of Calcutta aiding the city's poorest and sickest people. Since Mother Teresa had taken a vow of obedience, she could not leave her convent without official permission. After nearly a year and a half of lobbying( 游说, ), in January 1948 she finally received approval to pursue this new calling. That August, donning the blue-and-white sari that she would wear in public for the rest of her life, she left the Loreto convent and wandered out into the city. After six months of basic medical training, she voyaged for the first time into Calcutta's slums with no more specific a goal than to aid "the unwanted, the unloved, the uncared for." Which of the following statement is correct?
