We try to be aware and accepting of impermanence. Tibetan sand mandalas are probably the most popular example of tangible impermanence, as well as practice in non-attachment.* These painstaking and beautiful pieces of art, created over hours of meditation, are simply blown away.
My toddler likes to “find the rainbows” that the morning light sometimes throws around our house. The spectrum shining on the carpet or the wall isn’t always there, and it always changes and disappears. So young, we begin training ourselves in impermanence.
These are two beautiful examples, but life is about balance. Sometimes things aren’t beautiful. Maybe you have knee pain. Or the world is caving in and it seems you’ve been dealt a “sh!t sandwich” as some might say. We need to remind ourselves that ugly, unpleasant things are also impermanent. Even our own negative thoughts, self-criticism… these moments, these feelings…
Whatever is. Whatever was. Nothing lasts forever.
Note: While I use the sand mandalas as an example to illustrate a point, we can’t forget that Buddhism and yoga are not the same thing.
