The practice and understanding of impermanence is not just another description of reality. It is a tool that helps us in our transformation, healing and emancipation.
Impermanence means that everything changes and nothing remains the same in any consecutive moment. And although things change every moment, they still cannot be accurately described as the same or as different from what they were a moment ago.
When we bathe in the river today that we bathed in yesterday, is it the same river? Heraclitus said that we couldn’t step into the same river twice. He was right. The water in the river today is completely different from the water we bathed in yesterday. Yet it is the same river. When Confucius was standing on the bank of a river watching it flow by he said, “Oh, it flows like that day and night, never ending.”
The insight of impermanence helps us to go beyond all concepts. It helps us to go beyond same and different, and coming and going. It helps us to see that the river is not the same river but is also not different either. It shows us that the flame we lit on our bedside candle before we went to bed is not the same flame of the next morning. The flame on the table is not two flames, but it is not one flame either.
