The book does talk a lot about resentment like Cessie said.
For me it's sometimes easier to explain resentment to a new person as a "grudge list". This is one of those things that is a totally "human" experience that non-alcoholics have, too, like GeoffS said. But for me, alcohol did some damage to certain parts of my brain, now they don't work. So my mind has to learn how to become morally "rewired" or "re-taught" through applying the spiritual principles behind the 12 steps.
I had a "grudge" against a certain woman when I was a few years into sobriety. She was the perfect actress, blonde and beautiful, and I fell for her act. I found out she was, oh hell here goes another crazy thing I don't really want to share. Folks, let this be a warning about what happens when an alcoholic stops increasing his spiritual life through work and self-sacrifice for others, and when he stops working a recovery program.
Well my mind got deviant after I found out the truth about this woman who was expressing great interest in me, even buying me things. I got interested in her too. Well I came to find out she was a paid snitch for call it an "unamed" branch of law enforcement. I let that grudge grow into the biggest, fattest resentment. I planned out a crime -- use your imagination, please because it's painful for me to say again today. I was ready to carry out something really bad. I knew where she lived. I know "B & E", and a bunch of other unecessary "skills" that would have put me behind bars for a long time. I was dangerous.
Being "sober" without God is painful for me to remember and talk about. I can visualize things as I planned back then - I haven't forgotten who I was. I'm not proud to say that I could see myself, and the look on her face which I thought would bring me satisfaction. I wanted to watch her up close and personal. I wanted to "feel" and sense her fear - to smell her when she clocked out. A "payback" for what she did to me - a payback I thought all snitches deserved. That was what I thought would "make it right" in the universe. This was "passion" gone very bad.
I'm not proud of myself. I was without God's Direction. I wanted to make a person suffer, and to watch her, and even smell her fear. That's a thing that differentiates some alcoholics from everyone else. Over the years I drank, alcohol increased my spiritual malady - my sickness (or "hole") of the soul - to the point where I would enjoy doing something very ugly. That is a malady. That is a sickness of my soul.
Alcohol brought that about. Somehow, alcohol had an "abnormal effect" on some part of my brain to the point where I became capable, that is uninhibited enough, to carry out grizzly acts of violence against another human being, and then enjoy it. Somehow, alcohol damaged the part of my brain that controlled my dangerous or wreckless "impulses". I'm alcoholic and I was "suffering from an illness which only a spiritual experience will conquer."
Well something distracted me from my plans - obviouisly God had a hand in granting me grace. Somewhere during that time, I prayed again, and my destructive desire was lifted. All this went on after 4 years sober. Then a real irony came to me, and by that time, my innermost being had changed. I asked for help from God because I knew I would drink again, and deep within my heart, it hurt me to think and plan out a violent act against one of God's daughters. But my own twisted thoughts were there before me. I saw myself through God's eyes and experienced God's grace and mercy, and I changed.
I found out the girl had a serious mental illness that she was getting treated. She was mentally sick. Her mind was crushing her. A man I knew described taking her to her psychiatrist several times. He described how she was shaking and crying, and she would blurt out psychotic things - he had to restrain her to get her into the clinic. She wasn't an alcoholic. But she was mentally sick. Very sick.
I no longer had that "grudge" or the "resentment". I took her mental condition lightly, but I no longer needed to think destructively or hold a grudge, or have a resentment.
The ONLY way I can overcome the damaged part of my mind, my "broken inhibitions", is to pray the "4th step prayer" over on page 67 which goes like this:
"We asked God to help us show the same tolerance, pity, and patience that we would cheerfully grant a sick friend. When a person offended we said to ourselves, "This is a sick man. How can I be helpful to him? God save me from being angry. Thy will be done."
That's a pretty simple solution to resentment. It's not easy, but it is simple. For me it works, and it's not as uncomfortable once I learn how to do it through practice over and over again.
I LOVE SOBRIETY!
I discover freedom from the "bondage of self".
