Karma isn't a b**** or a mother f***** it is what you make it... if you say karma is a b**** or a mother f***** you're just giving descriptive adjectives of yourself.
Karma is not of another's actions, only of your own.
Don't be brainwashed to believe silly expressions you hear.
Be programmed to think about what you are hearing and listening to simultaneously. To listen means to hear and now process to see if what input is sensible and logical and rational. If you don't practice that already, start today immediately.
Who is brainwashing you and why and why would they like to make you so malleable and pliable???
Think and do for yourself.
