“All I have learned in the twenty years that I have been a monk I can sum up in one sentence. All that arises passes away. This I know.” conversation between monk and Eckhart Tolle in The Power of Now
Reminding myself that nothing lasts forever helps me to really enjoy the good times and not worry too much during the bad times. Knowing this also helps me move on from the past. Life is meant to come and go. If we focus too much on what was, we miss what is. Your life happens one moment at a time and it is all good.
