Nobody advertises this part. The photographs are all of the calm bit, so the first uncomfortable sitting arrives with no context and reads as failure.
It is not. These states are common enough that Buddhist traditions built a standard list of them well over two thousand years ago, and the list is recognisably the same one a person produces after a fortnight of sitting in a kitchen.
The old list
The five hindrances (nīvaraṇa) are sensual desire, ill will, sloth and torpor, restlessness and worry, and doubt.
Two things about the list matter here, and the second corrects something you will often see said.
First, these are catalogued as predictable obstacles, not as a sign of unsuitability. A tradition does not build a taxonomy of things that only happen to people who are bad at it.
Second, and this is the part modern writing often gets wrong: the classical texts do not simply recommend watching a hindrance until it passes. They prescribe specific active countermeasures, one per hindrance. Contemplation of the body's unattractiveness for sensual desire. Loving-kindness (mettā) for ill will. Tranquility practice for restlessness. Inquiry into the teaching for doubt.
For sleepiness the advice gets remarkably concrete. In one discourse (Pacalā Sutta) the Buddha gives Moggallāna a graded list to work down: change what you are attending to, recall the teaching, recite it aloud, pull your earlobes and rub your limbs, get up and wash your eyes and look at the stars, attend to the perception of light until night seems like day, walk, and finally, if none of that has worked, lie down deliberately and rest.
The bare-observation approach, where you simply notice a hindrance and let it be, belongs mostly to the modern insight movement. It is a real approach with real teachers behind it. It is not the whole of the tradition, and anyone telling you the old texts say only that is compressing two thousand years into a slogan.
What both approaches share is that the state is expected.
Restlessness
The body will not settle. Something itches. A leg wants to move, then the other one. Fifteen minutes feels structurally impossible and the urge to stand up arrives every forty seconds.
What people describe doing, roughly in order of how much it changes:
Look at it. Notice where the restlessness actually is in the body and what it actually feels like. It often turns out less solid than it seemed.
Wait a beat before moving. The middle position most people land on. Notice the urge, let it sit a moment, then move if it is still there. That way the sitting is neither a fidget nor a standoff.
Sit shorter. A restless fortnight is a reasonable time to use a smaller number.
Move first. A walk before sitting changes the character of it for some people. Walking practice exists as its own thing in several traditions for related reasons.
If restlessness shows up, give it a seat. It's allowed here too.
Boredom
Less dramatic and, for many people, harder. Nothing is wrong. Nothing is happening, and a mind accustomed to constant stimulation files that under intolerable.
Boredom is a reasonably interesting object once looked at directly. It has a texture, a slight pressure, and it arrives with the strong conviction that something else would be better. Turning attention onto the boredom itself is a standard move in several traditions.
And novelty-seeking is a large part of what sitting quietly is a break from. A dull sitting is doing the thing it does. The dullness is not in the way of the practice.
None of which makes it pleasant. It just is not a sign of doing it wrong.
Sleepiness
The fog. A sitting that passes with almost nothing to report, a head that keeps nodding, or the discovery at the closing chime that the last eleven minutes are missing.
Nearly always this is information about the day rather than about the practice. The hour, the meal, the week. The adjustments people make are the same ones on that ancient list:
- Sitting up rather than reclining, away from anything soft enough to lean into.
- Opening the eyes, or lowering them to a soft gaze at the floor.
- Somewhere cooler, or with more light.
- A different hour. Late evening is where most sleepy sittings live.
- Sitting shorter, since a shorter sitting can be sat through awake.
And sometimes the honest reading is that you are tired and a nap is what the day called for. Also allowed.
Doubt
The fifth one deserves its own mention, because it does not feel like a meditation problem. It feels like a conclusion.
It arrives as a perfectly reasonable thought partway through: this is not doing anything. Sometimes as this is not doing anything for me specifically, which is more convincing. It is the most effective of all of these at ending a practice, because unlike an itch it does not present as a passing sensation. It presents as having worked something out.
The classical handling is inquiry: look into the question instead of accepting the verdict from inside a quiet room. The modern handling is to notice it as another arriving thought and return. Either way, whether the practice is worth doing is a question you are better placed to answer on a day you are not in the middle of one.
The sitting you do not want to do
Distinct from all four. The day when the whole idea is unappealing before you have sat down.
The commonest advice is to sit anyway and make it short, the shortness being the concession. The second commonest is to skip it, on the grounds that a practice which is never optional slowly turns into an obligation, and obligations get abandoned wholesale instead of adjusted.
Both are defensible. What costs more than either is a long negotiation.
Stopping early
Always available. In Nanea a sitting ended in the first minute is not recorded at all, so you can sit down, change your mind, and leave without it counting for or against anything.
