When was the last time you got really mad at someone? …Really mad at someone for something you believed that they did?
 
When you got mad at them, did you ever question, “What is my responsibility in what happened?” “What part did I play in this outcome that led to my anger?”
 
Here is a fact about life, and a fact that few people choose to realize, people are who they are. All you have to do is to be aware enough to study who they are, what they do, how they interact with you, and how they interact with other people, and you will know what to expect.
 
For example, did you ever listen to the stories told by this person about their relationships with other people, before you became angry with them? If you did, most likely you would have been able to see what was coming between you and them. You would have been able to gage how their relationships with other people evolved and ended.
 
…Did you ever look at the life of the person you became angry with, before you became angry with them? What had they done prior to your/that interaction? Where are they in their life? Did they have established friendships, a stable lifestyle, and an established career? Or, was their life lost in the wind?
 
Again, people are who they are.
 
Yes, some people do lie about who and what they are. But, even when this is the case, if you take the time to study them, (their behavior, and their lifestyle), you will be able see through the illusion they present long before it becomes a problem.
 
What is anger? What is anger focused on another individual? Basically, it is based upon the fact that you do not like what that other person did. Now, this can be a small thing, or this can be a very large thing. But, the fact of the fact is, whenever you are angry, it is you who chooses to instigate that emotion in yourself. Thus, anger is always your choice.
 
This is not to say that it cannot be motivated by what someone does. But, it is you who chooses how to react to that life incident.
 
So, what does this tell us? The fact of life is, not everyone is going to behave in the way you want them to behave. People are going to do things you do not like. Though they may be the one to instigate the factors that created the emotion of anger within you, it is only you who chooses what you with that emotion.
 
A lot of bad things have been done based in anger. A lot of people have been hurt, and a lot of negative karma has been set in motion.
 
Ultimately, if you choose to feel the emotion of anger, (and it is a choice), what you do with it can not only come define the rest of your life but the rest of all those who encounter the reverberations of your anger. Thus, though someone else may have instigated what you are feeling, if you cannot keep that emotion under control and perhaps even transcend it, in may damage the next evolution of your life.
