Lama Ole’s answer:
Keep trying until the people don’t make you aggressive anymore. If you think about the fact that all people—even those who make you mad—can expect sickness, old age, and death, then your anger will turn into compassion.
Look at your antagonist like this: He was born, that hurt, he cried, he was so little and unprotected. During his life he had many wishes; some were fulfilled, others weren’t. Right now he wants many things he can’t get. He wants to avoid many things he can’t avoid. Maybe he wants to avoid you but you’re there anyway. And he constantly has to look after everything he owns.
If you have observed this closely, then you will realize that he’s badly off and has difficulties. You can develop compassion and see that this poor guy needs your help rather than an argument. Then you can step aside and let him hit the wall. Or you stop him in a way that is unpleasant for him. But when you react in this way, it must never be out of anger! You have to be aware that if he develops a habit of behaving badly, then it will be very difficult for him to change again. So stop him now.
You can handle people as you like, impress them, be charming, and so on, as long as you wish to liberate them. Check yourself! With compassion and the wish to be useful for others, you can apply your charm. And if you are free of anger, then you can be hard on others in order to help them.
First, always keep the liberating Buddhist view in mind. Then when you begin to see more clearly how people live, what they wish for, and how many difficulties they actually have, aversion will constantly decrease and your wishes for their happiness will increase.
