Recently I was in Disneyland with my kids sitting backwards on a roller coaster at fast pace doing circles. For some reason I felt relaxed and calm, so I closed my eyes and did some meditation.
The metaphor here is that life is a roller coaster. It is chaotic, fast, and has ups and downs. If you wait for it to go smoothly before you relax and enjoy the journey you will be waiting a long time. The time to enjoy it and be calm is now.
