Is it not funny? We think nothing changes, and yet daily, change happens. The Angels tell us that our bodies and minds are built to handle change. We were designed to accept change and find ways to manage how we would interact with the change.
The Universe gave us a a model to follow. Nature changes daily and has four distinct seasons of change for the flora. Weather changes daily, and has many patterns that it follows. Wind is the best example of the many patterns that weather can flow into.
The life lesson that change forces on us that change is most easily adapted if one goes with the flow.
