From the page: "There is a difference between speaking with anger and speaking your truth. When you speak with anger, know that the ego-self is speaking. Know that you're reacting to and focusing on an illusion you see as real. When you speak with anger you bring forth knowingly or not, emotionally repressed feelings from the past. You replace the present with the past and you lose the opportunity to experience what is really going on.
When you speak with anger, you are not really concerned with how those listening to you will feel. All you really care about is that your point of view is heard. When you come from such a place, all you are doing is making the listener defensive. The listener then puts up a wall to defend himself or herself against the perceived attack. As a result, you end up arguing or shouting at a wall with the hopes of being heard. Regardless of how smart or right you believe yourself to be, you will not be heard by a wall. Obviously, a wall is not a good listener, which creates frustration. The frustration leads to confusion, which then ends in regret. This person, knowing that he cannot communicate with you, will move on to someone he believes will listen to what you did to him. This creates more frustration and miscommunication on everyone's part. In short, whenever you speak with anger, regardless of whether or not you believe you have every right to do so, frustration, confusion, separation and regret are your end result."
