We all have our personal wall. It is initially built by our family when we are quite young. As we get older, we tear some of it down or we build it up even higher.
Tear it down too low and we will make our moral and ethical disciplines too easy to breach. Build it too high and we will impede our ability for healthy personal growth and discovery.
If you have built your wall at the right height, you will be able to just barely see over the top. You’ll have the spiritual confidence to know that your personal wall is high enough to stop you from doing something you will regret, but low enough for you to see the world as it truly is and therefore experience its beauty and its sadness. At that point you are not just aging, you are maturing.
