The Bridge of Life
Reb Moshe pointed to a bridge and explained that it was invented to let a person travel from one place to another safely, the bridge above and the churning waters of his tzoros below, carrying him to safety so that he comes to no harm. So too, we can cross life's tzoros safely by crossing on a bridge. Of such inventions and innovations of ruchniyus he simply claimed them as his own: "Mein patent." Those who knew him later understood that he himself crossed life on such a bridge. He had no family, no life, no identity, nothing independent, and they did not even know his last name at the time. It was his patent to make it across safely.
