Detachment

One of the Four Agreements is; "Don't take things personally".  This is speaking directly to our inclination to think everything that happens in our lives is either about us, or within our control.  In truth, very little that happens in our lives is a result of some action we have taken.  Life happens.  People make decisions all the time that can affect us.  It doesn't mean that we have to take responsibility for it.  If something does affect you, think of it as a temporary condition; it won't ever happen again just like that.  Let it go.  The river of life takes the event and the emotions away immediately when we allow it.  Holding on won't help.  Take that deep breath.  Breathe into the new moment, see what is here, now.  Letting go means not holding on.  This goes for the 'negative' and the 'positive'.  Let go of past happiness, too.  Clear the way for happiness in the present.
