Human beings can withstand a week without water, two weeks without food, many years of homelessness, but not loneliness. It is the worst of all tortures, the worst of all sufferings.
If you have a sick or lonely person at home, be there. Maybe just to hold a hand, maybe just to give a smile, that is the greatest, the most beautiful work.
We can cure physical diseases with medicine, but the only cure for loneliness, despair, and hopelessness is love. There are many in the world who are dying for a piece of bread, but there are many more dying for a little love.
