People who are endowed with chesed (loving-kindness) have something more magnetic than beauty or a handsome face. In Hebrew, we call this chein, an inner charm that radiates. Kindness illuminates their faces, and even if, with the passage of time, she becomes flabby and wrinkled and he becomes bald and potbellied, the chein, the charm, remains, and because of it, they will always find their partners enchanting. And that is the most important ingredient for a good marriage.
