An argument that lasts but a minute of your time does cause you to separate yourself from another for not just a minute, but for years.  You no longer speak to that other.  The body clenches at the mere anticipation of crossing paths, and when you do cross paths, you give a wide berth, avoiding the eyes and holding onto anger.  Why?  It is pride—a facet of the ego.  “I was right!” the ego screams, “and you were wrong.”  Perhaps, but now who suffers?  Two suffer, not because one was right.  What is “right?”  A perception based on beliefs.
 
Perception is changed in an instant, but stubbornness and belief cause you to hold onto anger, resentment, judgment, and pain.  If perception can change in an instant, imagine the instant change of seeing that the only thing that ever matters is love.  The only thing that never changes is spirit, which is born of love.  Recognize that the human is flawed.  The spirit is perfection in action.  The human is spirit striving to once again reveal its perfection. 
 
Release your grudges in a moment of grace.  Forgive your neighbor and you have forgiven your Self.  Do so in an instant and feel the love once again flow.  It is that simple.
