Our Egos have a way of surviving within us, creating a sense of identity. Its goal is to never lose. Its opinions, thoughts, beliefs, have a way or sense of a defense mechanism.
When we have discussions with others that have alternating views on specific topics (politics, religion, moral values, etc) we may have default feelings of defending our views. Really this is the work of the Ego in action.
The Ego desperately wants to defend the view, rather the view of the person its in, and dammit will it not let go if its hold if it can help it. Arguments, heated emotions, guilt tripping, fact checking, debating, and other tactics become exchanged between persons what is right and what is wrong.
We must aquire a sense of awareness that this is occurring because then the Ego loses its hold over us. We ourselves define what is good or bad, right or wrong, in the world around us. Once we define what it is, it becomes our reality.
I was told once when I was training to be a server that "The customer's Perception is our Reality"
I believe the redefinition is really "The customer's Perception is their Reality". In order for mutual peace to be in order we must take an awareness to our interactions with others that we all define our world, creating and defining our realiy. Become aware and lovingly respect the perceptions/realities of everyone; it is what makes our world interesting and beautiful.
See the peace and love through how the Ego/World fuels fear towards us; Awareness is the Key.
