Sometimes we humans can seem nonsensical. On the one hand we get bored. On the other hand we don't like change. And it seems the older we get, the less we like it. This is not a defect; it is our nature.
We are composite creatures: part physical, part spiritual. Our physical self is constantly in motion. Try to sit still and meditate for even 5 minutes, see how often the mind flits from one thing to the next. The Spiritual part of us seeks the Eternal, the unchanging.
The problem is when we try to find the unchanging in our physical world. We think that if we can make the world stand still, or turn back the clock, things will be better.
Every aspect of the material can and does constantly change. Even our hearts and minds change. If we are truly the person God calls us to be, we are constantly drawing closer to God. The only unchanging reality is God. We were created for him, to be one with him, and our soul knows this. We hate change because we know that our true home is with God. St. Augustine was correct, "Our hearts are restless, until they rest in Thee."
True happiness, true peace comes when we can embrace the changing nature of the world and ourselves, and simultaneously anchor ourselves to the Unchanging ONE, God.
