'Life is like the tide,' writes Venerable Master Hsing Yun, 'rising and falling with its pluses and minuses.' This reflects the Buddhist concept of impermanence, or constant change. Some changes, the Master says, are for the better, so they are easy to accept. But even changes for the worse - 'minuses' - have their place. Life's setbacks can improve our characters. And when we experience them we can learn to realize that minuses prepare the way for better things.
