People don’t make you angry, thoughts make you angry. You can’t be angry unless you think the thoughts that make you angry. If you win the lottery in the morning, who’s going to make you angry that day? No one.
No matter what they say to you, you aren’t going to think about them. You are going to be thinking of your winnings. You can only get angry with someone if you think a lot about them and what they are saying and doing and what a threat it is to your happiness. If you don’t think about that, how can you be angry?
Your mind is free. When you are angry, upset, grieving or whatever negative feeling has you, and the phone rings, and it’s your long lost best friend calling out of the blue, where do all those negative feelings go? They are absolutely gone! And that alone should illustrate to you that your mind is free.
