Karma works in the way that when you do bad things or treat others bad then eventually bad things will happen to you but if you do good things and treat people good then good things can and will happen to you.
Karma does really exist and I've witnessed it and known people who've received bad Karma for doing bad things.
Karma, a Sanskrit word that roughly translates to "action," is a core concept in some Eastern religions, including Hinduism and Buddhism.
With karma, like causes produce like effects; that is, a good deed will lead to a future beneficial effect, while a bad deed will lead to a future harmful effect.
I've also known people who've gotten good Karma for doing good things.
Do bad things and then you'll eventually have bad things happen to you and if you do good things then good things will happen to you.
It may not happen right away but it can happen years later.
If you want good things to happen to you then you should do good things but if you want bad things to happen to you then do bad things.
Eventually when you do bad things the Bad Karma will catch up with you either through you losing a loved one, getting into a car accident, suffering from an illness, death etc.
Bad Karma is when you have something bad happen to you as a result of doing bad things yourself.
For example you bully someone and call them names, etc and then eventually you lose a loved one or you get into an accident yourself.
That would be bad Karma.
I've personally witnessed bad Karma.
I had a bully in school who would always bully me and some other kids and eventually bad karma caught up with him.
As soon as he got his Drivers License he got into a bad car wreck with a semi truck and almost died.
He was very lucky to be alive and after the car wreck he apologized about his wrong doings and said that him being in the car wreck changed him.
So basically you get what comes to you for doing bad things.
There's also good Karma.
If you do good things then good things will come to you.
But if you do bad things then bad things will come your way.
