Say to yourself, or to the person you are teaching, that in a minute the talking stops and the doing begins. It sounds trivial and it removes the low hum of what is he going to make me do that keeps a wary person half out of the room. Build it in pieces, like anything else you have learned with your hands.

The physical object is what turns something happening inside you into something you can count. If you are doing this with someone over a screen, ask them to show you that they have it, because they will say yes out of politeness and then sit there empty handed. Set your things out the night before if mornings are the hard part.

The point of the image is that it gives you somewhere to sit. Being told to observe your thoughts is abstract, while a bank and a river gives your attention an actual place to stand and a direction to look. Nothing in the water has to change. You are only practising being the one who watches it, which is much easier than it sounds when nobody has given you a spot.

Knowing the name matters more than it should. Plenty of people, and especially people who were sent to get help rather than choosing it, quietly file this kind of exercise under soft nonsense and stop turning up. A technical term is a small piece of evidence that somebody serious has looked into this, and that is often enough to keep a doubtful person in the room long enough to try it.

This is the most common way the practice goes wrong. People build a lovely picture of a stream, get bored of it, and decide the exercise does nothing for them. Skip the scenery. Close your eyes if you like, look inside, and just register what is there right now: a thought, a twinge in your shoulder, a bit of a song. That is the whole job.

The dot is doing something specific: it turns a private, slippery moment of noticing into an act you can see and count. No words, no keeping score, just a mark and back to the bank. When you drift off with the current, and you will, the dot is also how you come back, so drifting stops being a problem and becomes part of the loop.

Fast minds are common and they are not a disqualification. When too much is going past to mark, mark that. The exercise is not a race against your own head, and the moment you notice you are behind is itself a moment of noticing, which is the only thing being trained.

People who are hard on themselves will turn anything into a test, and a test is the one thing that will wreck this. You are not aiming for a tidy page or an impressive count. If you catch yourself grading the session, that thought gets a dot too. A practice you can do badly is a practice you will keep.

The moment you start describing a thought you are back in the water with it, sorting and explaining and defending. What you are training is the vantage point, not the material. It also means nothing private ever lands on the page, which makes the practice much easier to do honestly when you are somewhere you would rather not be understood.

Metaphors are personal and there is no prize for liking the poetic one. Some people take to it straight away when it is a road and a stopwatch instead of water and a bank. Keep two or three images in your pocket and use whichever one lets you sit still and count without arguing with the idea.

A minute and a half is short enough that a restless or reluctant person will agree to it, and long enough for something to happen worth talking about. Do it, talk about it, then do it again with a small change. The other advantage is obvious once you are at home: ninety seconds is a length of time you might actually find on a Tuesday.

People come back with all sorts: restful, stressful because my head is so fast, mostly sounds and aches rather than thoughts, strangely reassuring. None of those is the wrong answer. If someone says the thoughts felt like just thoughts, without all the meaning stuck to them, that one is worth pausing on, because that is the thing the whole practice is for.

Nearly everyone assumes the aim is a quiet head and then quits when the head refuses. Change what you are counting. Quiet is not something you can produce on request, and returning is something you can do all day. Ten dots means ten returns, and next week's twelve is not worse than this week's eight.

This is the part that offers something to people whose sense of themselves rises and falls with how they were treated that day. If who you are is the watching rather than the passing content, then a bad hour, an insult, a mistake at work, none of it revises you. You can take that as far as you like philosophically. Practically it loosens the grip of needing everyone to give you your worth back.

Write the key at the top of the page so you are not holding it in your head. The sorting is useful because putting a rough name to something is often enough to loosen it. If deciding which letter takes more than a second, put a plain dot and move on, because a practice that turns into analysis has quietly become the thing it was meant to interrupt.

Thoughts slide past before you can get hold of them, feelings blur into each other, and body sensations are vague. An urge announces itself, because part of you has already begun getting ready to move. That turns out to be lucky, since in anger the urge is the thing that gets you into trouble, so the easiest thing to catch is also the one worth catching.

Your mind tags things before you have had any say in it, and anger tends to follow the tag rather than the event itself. Sitting for a few minutes and marking each passing thought as a plus, a minus or just a dot slows the tagging down enough that you can watch it happen. Do it often enough and the dot starts to feel available in the middle of an ordinary day.

This is easier to practise with praise, because praise feels harmless. Notice how much you want the good tag and you begin to see why the bad one has such a grip: they are the same appetite. Nobody drops it altogether. It does loosen, though, and the looser it gets the less an insult has to work with.

You can sit quietly and watch your own mind with real steadiness, then lose the lot the moment somebody smirks at you. That is not backsliding. It is a different exercise, and it needs its own practice, in small doses, with actual people. The quiet work makes the room; being around someone difficult is what teaches the room to hold.

People take the quiet as proof they have finally cleared their mind, then feel cheated when the noise comes back. It never left. Attention was resting on something plain, so there was less to react to. Expecting that, rather than a blank mind, saves you a good deal of disappointment later on.

A written page holds you to it. The marks are still there afterwards, and there is no pretending you drifted for ten minutes. So learn it that way first, until the noticing is second nature. The tap is for taking it out into the world once the noticing no longer needs propping up.

The props are there to teach you what noticing feels like, not to be carried around forever. Once you can tell the difference between being inside a thought and watching one pass, the marking has done its job. Some days you will want the pen back, and that is fine. Nobody graduates from this permanently.

A first go that actually works gives you a reason to come back, and plenty of people never do come back. But one sitting builds nothing on its own. Whatever changes comes from the small amount you do in between, on ordinary days, when nothing has happened yet.

Some people hear anything that sounds spiritual and close the door, and then a useful skill goes unused over a word. There is nothing here you have to believe. You sit, you watch what passes, you mark it. If you are offering this to someone who would sneer at it, use their words rather than the ones from the book.

People apologise for getting sleepy, as though they failed to concentrate hard enough. The heaviness is your alarm system standing down, and it is a signal you can feel for yourself without anybody interpreting it for you. If it happens every time and you would rather stay alert, sit upright with your eyes open in a cooler room.

Fighting a signal you cannot switch off lays a second misery on top of the first. People who live well with long term pain tend to do something else with it. They let it be there, at a slight distance, without handing it the whole day. The same handling suits an anger with nowhere to go, about a person who is gone or a thing that cannot be undone.

Words matter here more than they should. Call it wise and some people hear weak, and reject the skill along with the label. Whatever you call it, the state is the same: you can see clearly, you know what you want, and you are not being driven. Find the name for it that you would not be embarrassed to use in front of your mates.

The same watching works on wanting, on worrying, on the hour you lose to your phone. Anger is just the doorway you came in through, usually because it caused the most trouble first. Not everyone wants the larger version and there is no need to take it. If you do, it stops being something you were told to do and becomes something you keep.

The picture is not killing the anger off. It is closer to getting a big animal under control and walking it home: still strong, still yours, going roughly where you point it. Plenty of people only ever do this once. If that turns out to be you, the thing worth keeping is the memory of the moment you had hold of it.
