Three different operations go by this one name, and they do not do the same thing.
My name is Ren Kagetsuki. I spent fifteen years building the things these are used against, and then the years after that taking them off people.
Mirror. Return. Undo.
Pick the wrong one and nothing happens, which is what most people mean when they say a reversal did not work.
The first kind: the mirror
A reflecting surface set between you and whatever is arriving, so that what comes does not land.
Every tradition has a version. A mirror at a window, a mirror box, a reflective charm worn on the body.
What it does. Deflects what is currently in flight. It is a shield, and shields are genuinely useful.
Where it stops. It does not close the road. Whatever is being sent is still being sent, and it is still arriving. It is simply bouncing.
People run a mirror working, feel better within days, and then find it flattening out after a few weeks. That is not the mirror failing. It is a shield doing a shield’s job while somebody keeps pushing.
The second kind: the return
The same thing that arrived is turned around on the road it came down and sent home.
What it does. Ends what is on you and, in most cases, ends the sending, because the person at the other end receives what they made and stops.
Where it stops. There has to be a sender. Trouble belonging to a house, to land or to a family line has nobody at the far end and a return finds no road.
The full rite, including what to do with the mirror afterwards, is here: the complete return to sender ritual.
The third kind: the undo
Taking apart a working rather than deflecting or returning it.
Hardly anybody writes about this one, and it is the one I get asked about privately more than any other.
Because usually the person asking is the one who built it.
They sent something during a bad month. The situation has since changed, or the anger has gone, or they have simply had enough of carrying it.
There is no shame in that conversation and I have had it many times, including about my own work.
Undoing something you sent yourself
You cannot un-send it. What you can do is withdraw the thing that powers it, which is the wanting.
A working built around a wish runs on that wish. Take it back properly and the working has nothing left to run on.
The form
1. Wash first. Coarse salt, hot bath, fifteen to twenty minutes, rinsed downward.
No bath is not a problem, and most of the world does not have one. Coarse salt in a bowl of hot water, poured over the shoulders and let run down in the shower, does the same work. Or salt held in wet palms and worked over the back of the neck, both wrists and both ankles, then rinsed off from the head down.
2. Write down what you wanted to happen. Exactly, in the words you used at the time, however ugly they are.
This is the part people try to soften, and softening it is what makes the undo fail. You are withdrawing a specific thing and you have to name the thing.
3. Underneath it, write that you take it back. One line, present tense, no conditions and no explanations.
4. Burn the paper and put the ash outside on bare ground. Not the bin, not the sink.
5. Salt at your own door for three mornings afterwards, changed and thrown out each day.
6. Do not contact the person. Not to apologise, not to check on them, not through anybody else.
An apology is for you. It puts a live line back between you and them at the exact moment you are trying to close one.
What an undo will not do
Two honest limits, and you should have both before you start.
It does not repair what already happened. Withdrawing the wanting stops the supply. It does not give somebody their year back.
It does not reach work a practitioner built for you. If you commissioned it, the construction is not yours and your withdrawal does not take it apart.
That second one catches people. Go back to whoever you paid, or have somebody else unbuild it.
It is not a strange request and any practitioner who reacts badly to it is telling you something about themselves.
The precautions that actually matter
- No name, no face, for the mirror and the return. The moment you supply the aim, you are sending rather than reversing.
- A name is required for the undo. The opposite rule, because you are dismantling something you made and you have to be specific about what.
- Wash before any of the three. All of them run badly on a body that has not been cleared.
- Tell nobody while it is running. Least of all the person concerned.
The second one is the one that surprises people, and it is the clearest illustration of why these three are not one thing.
Which of the three you need
One question each.
Did you build it? Then it is the undo, and nothing else will touch it.
Is somebody still sending? Then the mirror buys time and the return ends it.
Is there nobody at the other end at all? Then none of the three is your instrument, and what you need is a clearing: what a reversal does and when it rebounds.
If you do not know which, tell me when it started and what has been happening, and I will tell you which of the three your case is.
And if you are writing because you sent something and want it undone, say so plainly. I am the last person who is going to think less of you for it.
