There are times in our lives where we feel that someone has hurt us tremendously and they deserve karmic law. Know that karma does exist and it will happen with time, regardless of any action on our part. However, if you would like to have it be a bit more expedient, and it makes you feel safer to commit to a karmic spell, there is an example here on spellsofmagic.com
As with all spells, you must understand that what you send out will come back to you. I have done a karmic spell without realizing it. Did it work? Well, let’s just say that the person who did the injustice to me felt consequence within three days. And the emotional pain he put on me, he felt 3 fold. While I did not want him to hurt per say, because that is not what is in my heart, I felt hurt and wanted that pain to travel back to him….so hopefully he would leave myself and my children alone.
With all you do, try and practice with a pure heart.
