One example of a quote about love is "Being deeply loved by someone gives you strength, while loving someone deeply gives you courage," by Lao Tzu. Another example is "Spread love everywhere you go. Let no one ever come to you without leaving happier," by Mother Teresa.
The quote by Lao Tzu depicts how being loved by another allows a person to draw on that love for strength when in need. It also implies that loving another being provides a source of courage when facing the unknown because that love inspires a person to act on behalf of the beloved. Lao Tzu was an ancient Chinese poet and philosopher. He is considered the author of the "Tao Te Ching," which is a text that describes the source of all life. It is also a significant treatise in Chinese cosmogony.
Mother Teresa's quote implies that it is part of the purpose of life to love people and help them be happy. She was a Roman Catholic sister and missionary in the 20th century. Mother Teresa won a Nobel Peace Prize in 1979 and founded the Missionaries of Charity, which consists of over 4,500 sisters, as of 2012. These sisters work in many countries, running homes and hospices for people with serious diseases.
