Rabbi Harold Kushner was watching children build a tower out of sand on the shore. After they finished their imagined tower, which took a lot of time and patience, a wave came and leveled it in an instant. The rabbi expected tears and anger, but instead, the children sat down, held hands, and began to laugh.
Shortly after, they started building a new tower.
He smiled and said, “I learned a very important lesson from them. All the things in our lives that we create for a long time and with a lot of energy are created in the sand. Only our relationships with people are permanent. Sooner or later, a wave will come and take away what we have built with so much effort. When that happens, only those who have someone to hold hands with will be able to laugh.”
