You knw it can be true that it can back lash.. even though now i know that i was betrayed, sending out negative energy could harm me on a long run basis.. So mabe, just mabe i must forgive, forgive and send positve energy. Dont wont bad karma. So, what i am emplying to is, is positive energy, results in positive results. So, how then?
Why do you want to send positive energy to those who have harmed you? It's enough to forgive them at least in my opinion. Work on healing yourself from the hurt that they have caused you instead if you are worrying about anything affecting you in the long run. There are lots of traditions with healing spells and there are many healing spells on this website that can help you. Take a look around and good luck!
Perspective works in the world of illusion and both are changeable. what is not able to be changed is truth. What I'm saying is that if you believe the threefold law is true you will be effected by if and if you don't then you might still be effected by it or you may not. This would be determined by if its a universal truth or if its an illusion. Point being that if you cannot distinguish between illusions forming around your perspective to support placebo effect and truth then we will be stuck arguing over what is true and what isn't. Which wastes valuable time and is quite frankly annoying. The three fold law does not make sense as one wrong is not equivalent to another. Even when I believed in it I found it was drastically different in terms of how much karma comes back. For the literalistic out there I once gave a stranded family twenty dollars. the next day I do walking down the street and found a hundred dollar bill on the side of the road, never happened to me again by the way. That's five times not three. This is just one example and a statistically perfect one at that. That being said karma is quite specific in its dealings both good and bad. There is a balance that only karma gives. And it does not require us to act on it. Its actually quite ironic to speculate on. Whatever the people did to you it will come back on them. Life is a learning experience and if they are the type that cannot learn I'm sorry to say but unless they are acting as a catalyst for fate, which they wouldn't know. Then they are in for one s**ty life. But not as bad as if they are a catalyst. Anyhow if you get yourself mixed up in it then your are putting yourself in the same position. If theres one thing I learned from working with negative energy, its that there is no possibility for negativity to be used as possitivity. Hatred only breeds more hatred, and an eye for an eye makes the whole world blind.
Im realy happy you decided not to take revenge. I was praying for you. What you mentioned they did to you didnt sound worthy of a hex or curse to me, even if you were angry and hurt. Theres other less harmful ways to deal with stuff like that, which could be undone later if you choose like binding or freezing spells. Or even sheilding and protections for yourself.
