How people treat you is their karma; how you react is yours. ~Wayne Dyer
The good and the bad that you put into the universe always finds its way back to you. This is why it’s so important to be kind to others, even when they sometimes don’t deserve it. Once you mistreat someone, you’ve committed an act that you can’t take back. Your karma could mean suffering the same treatment OR living with the guilt of something you can’t undo.
Remember, like attracts like so always do your best to treat others how you want to be treated!
