The way I understand and experience ANGER is like this:
1.
I feel un-happy, somehow not satisfied.
(this applies to various degrees, it can be that I am depressed, or that I lost money, or that my bike got stolen, or I have physical pain, maybe someone punched me, or I fell from my bike, or I am ill...)
(in fact for sentient beings like us, it is a feeling that is pervading most of the time)
2.
I am ignorant, for I do not look in causes for this un-happiness in me, but I look "outside".
(what food gave me that cancer, who punched me, my father was mean and that is why I am depressed...)
3.
I have identified (erroneously) an object as the cause of my un-happiness.
(the guy who just over-took me on the highway, the colleague who gave me a nasty look, or even an object like my phone which "refuses" to switch on...)
4.
I nurture a mind of retaliation, a mind of anger
("You are going to regret what YOU did to ME!" and we even retaliate to a mobile phone throwing it with rage across the room and stepping on it...)
5.
Anger = the will to hurt someone or even something.
I think that somehow to hurt the guy who just overtook me on the highway will ease my un-happiness and I even dare to think that this will make me happy!
Our thinking is so bias that we even think that murdering someone will bring back our peace of mind.
6.
We act, we hurt, we deceive.
We like it in the moment.
We are "in charge".
We are "in control".
"problem solved!"
Anger = ignorance in motion.
What happens after is:
A. we experience the same thing again (un-happiness), as we created the causes to experience it because of the way we dealt with it.
B. out of habit, we deal with the situation in a similar fashion (anger).
C. eventually it spins out of control, up to a point where we loose our ability to analyse the situation and to develop alternative thinking about the solution to the problem.
Unfortunately, the problem for me is that I realize the above AFTER I have acted...
So part of the solution is to watch our train of thoughts BEFORE we have justified anger in our mind, that is NOT TO IDENTIFY AN OUTSIDE OBJECT as the cause of our pain, loss or suffering, but to recall karma to my mind at that point, to recall the lamrim teachings, to recall my guru's advise too.
And eventually to recognize that the problem is not solve by hurting someone else in retaliation, on the contrary it is made worse.
example:
If I want to get rid of the guy calling me names, I MUST STOP calling him names back.
Then the karma will simply exhaust and this experience will end.
