Nothing is permanent

Did you know that {according to Buddhist philosophy} there are 3 basics facts of all existence? 
The first one, the very core of Buddha's teaching, is Anicca or impermanence. It's also the basis of the other two, Suffering and Not-self {more on these later} 
We cannot say "this is lasting" for anything..ever.. Because even when you're saying it, whatever "it" is , is undergoing change. Everything is fleeting. You aren't anxious, anxiety is present. You aren't afraid, fear is present. AT THAT MOMENT. 
Isn't that comforting? It's much easier to get through a stressful situation knowing that it will change. It may not necessarily change for the better but it WILL change 🙏🏻
