What is the treasure of youth? It is struggle; it is hard work. Unless you struggle, you cannot become truly strong. Those who fight hard during their youth will have nothing to fear when the time comes to put the finishing touches on their lives. They will possess a great state of life that towers strong and unshakable. In Buddhism, we call this the state of Buddhahood, which nothing can undermine or destroy. It is a state of mind enjoyed by invincible champions of life.
