The rite itself takes about ten minutes. The week around it is what people get wrong.
My name is Ren Kagetsuki. This page is the practical wrapper: when to do it, what to have ready, and how to tell afterwards whether it took.
That last part is the one nobody writes down, and it is the only part that tells you what to do next.
Choosing the three nights
Three consecutive evenings you can actually protect. That is the whole requirement and it is the one most often broken.
- After sunset, same hour each night. Within half an hour is close enough.
- Not the hour between two and three in the morning. That window belongs to the sending side of this trade.
- Not on nights you will have been drinking, and not on a night you are expecting to be angry. A court date, a family dinner, a meeting with them.
- Not during a week that is already breaking. If there is a crisis running, do the washing and the salt now and put the return in a fortnight.
Two nights and a gap is not the same working. If a night is missed, begin the count again rather than continuing.
The day before
Everything decided in advance, so that nothing is being chosen while you work.
- Coarse salt, enough for three baths and six mornings of door salt.
- A hand mirror you are willing to throw away on the third night.
- Two small plates and a cloth bag.
- The line, written on paper. Decided now, never edited later: the grammar the sentence has to follow.
- Today’s date written down, with one line about how things stand.
That last item is the measurement, and without it you will have no way to read the result. It takes twenty seconds and almost everybody skips it.
The sequence, each night
1. Wash. A handful of salt in a hot bath, fifteen to twenty minutes, rinsed off from the head down. No bath is not a problem, and most of the world does not have one. Salt in wet palms over the back of the neck and both wrists, rinsed downward.
2. Guard. Roasted salt in the cloth bag, on you. Cones on the two plates at the door.
3. Locate. Three slow breaths, then attention from crown to feet in order. Heavy, cold or prickling.
4. Return. One hand on that place, mirror in the other facing away, the line said aloud three times, one breath each. Three rounds with a pause between.
5. Stop. Put it down, sleep, and do not do anything else that night.
On the third night the mirror leaves the house, wrapped face down. The reasoning behind each step is set out here: the full return to sender ritual.
The signs that it took
In this order, and the order matters more than any single sign.
- Days one to three, sometimes worse. Heaviness, sleepiness, a mild illness that comes and goes. Here that is called kouten hannou and it is read as leaving rather than as a setback.
- Sleep moves first. Within three nights. You stop waking at the same hour, or the hour shifts.
- The weight goes next. Over a week or two, across the shoulders and the back of the neck.
- Then the house. People notice a room they had been avoiding without having noticed they were avoiding it.
- The timing last. Things stop failing on the days that matter. This is the one that convinces people.
Feeling nothing during the rite is not a sign of anything. Most of the cases I have closed felt like nothing at the time to the person involved.
What is already lost stays lost. A return stops the adding to it.
The signs that it did not
Three patterns, each with a different meaning, and the timing separates them.
- Quiet, then back inside three weeks. The route reopened. Something is being fed and a return without a seal is temporary by design.
- Nothing changed at all. It is probably not on you. Look at the building or at the generation above you.
- Worse after a month, in the shape you wanted for them. Intent got into it. That is a different thing and it comes off differently: what strength actually is, and what it costs.
None of the three means you performed it badly. They mean different things were true about the case than you assumed.
The fortnight after
Four rules, and the first two do most of the work.
- No contact, in any direction. Including through a mutual friend, and including looking at their pages.
- Tell nobody. A working spoken about loosens, and that is the one old piece of advice I have never seen fail.
- No second working. Not a jar, not a candle, not a different version because you are impatient: why a second container makes it worse.
- One line a day. What happened, not how you felt. Mark the day the quiet starts and the day it ends.
Those two dates are a better description of your case than any list of symptoms, and they take a fortnight and a pen to produce.
Send them to me with what you ran. I can usually tell you from the gap alone what you are dealing with.
