Dasun was a poor boy who sold newspapers every day to support his family. One day, feeling faint from hunger, a kind woman gave him food and drink. This act of generosity inspired Dasun to study hard and become a doctor. As a doctor, he remembered the woman's kindness and sought her out to thank her. He went on to dedicate his life to helping others through opening an elder home, providing food to patients, and helping poor families. The story teaches that one should always help people, be good and kind to all in society, and work to better one's community.
