Analysis on Irritation or PMS (for short)

Was talking to my mum on the bus yesterday. Was trying to seek guidance from her. Now, anyone who knows my mum knows that my mum is a very "enlightened" mum... the kind you see on TV who always dispenses good advice, who loves us all to bits.. ie. the best mum in the world. Probably the only reason why I am the person I am... anyway...

I was telling her... how do I deal with the fact that I am easily irritable? I dun want to be irritable because, I dun like the feeling of being irritated. You feel like you want to snap out at somebody, but generally, the feeling of irritation stems from the fact that you cannot lash out at the actual person who actually irritated you. So you end up being foul and irritated to the innocent people. Which is really unfair. But I was also telling her, this feeling of fustration and irritation remains in your stomach.. until... you irritate the hell out of yourself from trying to repress it! Talking bad about others is self inflictingbad karma.. so what's a person gotta do?

And her answer is:

I must learn to let go. dun allow yourself to get irritated. cuz the other party doesn't even know or care that you're irritated and that I am harming myself by allowing myself to get irritated. Easy to say, difficult to practice.

Then I tried to argue with her, saying, "but if the other person deserves to have some form of retribution, or if that other person REALLY was the one in the wrong, then I am allowing the other person to get away with it, then, it's so unfair!!"

Her answer: That's why you have to left go. Because, this person will get his just retribution soon.

I sorta get it, although I am not very sure if I can practice it. I understand.. that the point is IF that guy is really wrong by laws of nature, then he/she will be struck by lightning soon, whether this life or next. But you dun have to be the one to accumulate bad karma by killing him, scoffing him (doubt i can contain this part) or by whatever... i shall try...
