Love and Attachment gives grief and sorrow

If you don't want to suffer from fear, anger or sadness, don't get attached to anything or anyone, to any expectation, any item, any particular outcome (result). That does not mean you shouldn't have possessions.
It does not mean you can't have people around you that you love. Nor does it mean you don't have expectations, goals, etc. You do. Your happiness does not have to depend on others & things.Dependent on any of them loose your peace and happiness. You choose to be peaceful and content in yourself only.
So when possessions are damaged or when people leave or die or when expectations are not met, all of which are inevitable, you don't become discontent. You have realized everything in life comes and goes, everything decays, every dynamic process is unpredictable and uncontrollable, and must end. You know this is a reality. Every time you get angry it means you are having an argument with this reality.
