In the dimension of duality that we live in change is an inherent part of life experience, where everything has an opposite. Accepting change is not necessary; change happens, whether we want it or not. But acknowledging it creates less resistance when the change is painful or unwanted, and when we're not in resistance, we can more easily see the benefits. Even if we can't see them right away, just knowing they will appear in due course simply because Life is good! Even if life experience feels bad, it will lead to peace of mind.
