Even the most beautiful or well-built sand castles crumble as the ocean tides wash across them. Foundations are destroyed, spires fall to the ground, and the footprints of the master architect are washed away. The things that we try to hold onto slip away or vanish, as does life itself. Yet it is death that gives life its meaning. A sand castle would not have its special charm or perhaps be appreciated as much if it merely went on standing, day after day, year after year, century after century. That which we take for granted are eventually taken away, and we are left with nothing. Even the body turns to dust. Those that are wise appreciate the now, what is in front of them. It is useless to cling and painful to try to hold on to what inevitably will be lost.
