We work hard to acquire stuff, help those we love be ok, give our best to our families and career and we feel good about that. Life by its very definition is evolutionary so nothing is permanent. All relationships by definition evolve in a dynamic way. Our houses and buildings serve their purpose for so many years and then they are replaced. So we live in an ever moving dynamically changing environment.
It just looks so solid. It looks like where we are is perfectly ok. It is for the moment.
Yet, like the tides of the ocean everything comes in and goes out.
When you hold the idea that letting go is something that can free you then you are totally present to the dynamic situation that you are in.
Now that is freedom.
