They say to turn the other cheek. If life gives you lemons to make some sour drink. I say bite back bitch! If the infraction is slight then, of course, let it go and move on. Too much energy can get wasted on a bunch of douche bags, why bother. If the deed is nasty and you know they should feel some pain then this is your piece.
Here is how it works. If your man cheats on you then you can show him a time that matches what he did to you. You can use this on your nasty boss, your horrible doctor or anyone you know needs it. Let the snake rise up and take a bite out of crime!
There is no karma for you when you use this. This is safe, has no rituals and no charging needed.
