Stopping mental fabrication isn't about suppressing or adding anything; it's about using mindfulness to go and know the truth at body, feeling, mind, and dhamma, so it dissolves on its own. Sitting meditation and daily mindful awareness work best trained together, each strengthening the other.
Someone asked: they wanted to understand the mechanism of the mind correctly when something makes contact, so they could practice more precisely — when contact touches the five aggregates and the mind, what arises first and what follows? At what point do the three natures step in? Where, exactly, can and mental strength go in to see and stop the mental fabrication — or should one simply know, without suppressing and without adding, and let it arise, stay, and pass away on its own? And how do sitting meditation, daily mindful awareness, and the ten-item homework help build mental strength and purify defilement? Is practicing awareness while walking, working, or doing other activities just as continuous a practice as sitting meditation — and how should one train so that mindfulness arises faster, so the mind has strength and isn't dragged around by emotion?
Phra Ajarn answered:
How the Mind Works When Something Makes Contact
When something makes contact — the eye sees a form, the ear hears a sound, the tongue tastes, the nose smells, or the hand touches something — that is contact with the five aggregates, which are simply body and mind. We already know ; the mind is made up of four things: feeling, memory, mental formation, and consciousness.
These four are like a computer. Think of your phone: the moment you switch it on, the first thing it tells you is which operating system is running — Android or iOS. That is the job of feeling, the outermost layer of the mind — it reports which system is currently running: wholesome, unwholesome, or neutral is in possession, acting as the “owner of the house” in our mind.
Next the device needs memory — that is what Buddhist teaching calls memory-perception. And it needs a processor — that is mental formation, the thinking itself, with mind and s layered right on top of it; this is the real engine doing the processing. Once processing is done, consciousness carries the result out — into image, into sound — through eye and ear, and so on.
Feeling Is the Sensor That Tells You Who's in Charge
Among the three natures competing for control, whichever is subtlest and fastest gets in first and takes charge. It begins the moment feeling — that outer, first layer of the mind — registers which one has taken over: wholesome, unwholesome, or neutral. If wholesome is in charge, its quality is happiness and ease. If unwholesome is in charge, its quality is a state of suffering — hard to bear, hard to endure. Neutral is simply neutral, neither pleasant nor painful. Feeling only ever carries these three flavors; it is the sensor telling us who currently possesses our mind.
While is in possession, we have no power to do anything at all — not until wins the house back. The moment it does, mindfulness arises together with the wholesome mind, telling us to do this, do that. Mindfulness only ever arises together with a wholesome mind; it is a mental factor that co-arises with wholesomeness. Whenever wholesome takes charge, that is when we have mindfulness — which means we depend entirely on the wholesome to train it at all. Nothing else can teach us mindfulness. If we don't train, that strength never builds. But if we keep indulging the unwholesome — , aversion, delusion — it is the unwholesome mind's strength that grows instead.
Where Do We Stop the Fabrication? — By Going In to Know Body, Feeling, Mind, and Dhamma
We use the mindfulness and wholesome strength we've already built up to go in and see the truth at the body, at feeling, at mind, and at . Because when one of the three natures takes possession, it brings its own whole set — body, feeling, mind, mental factors — and overlays it onto ours: its body controlling our body, its feeling controlling our feeling, its mind controlling our mind, its mental factors controlling ours. Mind, in other words, is never just one thing — there are said to be 121 kinds of consciousness. Mental factors are the mind's instruments; when the mind is unwholesome, its mental factors are unwholesome too — greed, aversion, delusion, lust, . When the mind is wholesome, its factors are wholesome as well.
Think of watching a drama. The actors step into a scene and play their roles, speaking their lines. When a character is written as good, their feelings read as good too — thought and feeling are two different things; a good thought produces a good feeling. Mind is the thought; it shows up as feeling. If the mind isn't good, the feeling isn't either — boredom, tightness, stress, irritation, exhaustion, discouragement, hopelessness, restlessness. But when the mind is good, when the thoughts are wholesome and right, the mental factors that follow are things like ease, release, spaciousness, openness, lightness, fullness, brightness, freshness, clarity, coolness, and .
The moment we go in and truly know, truly understand what's happening, that very act of knowing establishes an unbroken thread of awareness — and that strengthening mindfulness draws in to dissolve whatever defilement is there, lightening it. As for “don't suppress, don't add” — really, there's no one doing either. There's a cause behind it, some nature currently taking hold. So simply going in to know, to see — mindfulness arises, merit is drawn in, defilement dissolves — and the fabrication stops on its own, automatically. All it takes is going in to know.
The Buddha never taught, “Monks, go and eliminate this.” He taught, “Monks, you should clearly know body, feeling, mind, and dhamma” — for the purpose of removing and grief. The purpose is removal, but he never instructed us to do the removing ourselves — go look, go see, and it removes itself. There is nothing else to do but go and know: know the body, know the feeling, know the mind, know the dhamma.
At the start, this is simply the four foundations of mindfulness — knowing the body this way, the feeling this way, the mind this way, the dhamma this way. Later, the Mahapatthana Sutta takes it further, more intricately: contemplating body in body, feeling in feeling, mind in mind, dhamma in dhamma — seeing how another nature, like a guardian, overlays its own body, feeling, mind, and dhamma onto ours, controlling us to behave a certain way. “Body in body” means their body controlling our body, overlaid on top. “Feeling in feeling” means their feeling overlaid on ours, controlling it. “Mind in mind” means their thought layered into our thought, so it seems like our own idea. “ in dhamma” means the mental factors that generate states like greed, aversion, delusion, and the hindrances, overlaid onto our own mental factors, making us controllable.
Sitting Meditation, Daily Mindful Awareness, and the Ten-Item Homework
Sitting meditation builds mindfulness and wholesome strength, moving us from the coarse dimension toward the subtler one. Daily mindful awareness completes our mindfulness and , drawing pure energy in continuously and bringing about purity and release. The two are actually quite similar — sitting meditation just requires closed eyes, which makes drawing that purity in easier and more concentrated. Daily awareness, meanwhile, is about understanding the truth of the natures governing all beings. Sitting meditation gives rise to release through concentration; daily awareness gives rise to release through wisdom.
The ten-item homework also helps build mental strength and purify defilement — each item draws energy in, letting the wholesome take hold and layer in, drawing energy that purifies defilement automatically. The wholesome does its own work, bringing about purity on its own.
How to Build Mindfulness Faster and Stop Being Dragged by Emotion
Practicing awareness while walking, working, or doing any activity is just as much continuous practice as sitting meditation — it's the same principle as walking meditation. Other activities work the same way: they help concentration settle well, so that when you do sit, you sit better. Skip awareness during activity, and sitting becomes hard. But train awareness while walking, working, doing whatever you're doing, and sitting becomes easier and settles faster. Once you've sat, carrying that awareness back into activity works even better too — it's a cycle, each side supporting the other, improving continuously. Rely on sitting alone, without daily awareness, and sitting itself becomes difficult.
That's also why sitting sometimes goes well and then, after a gap, goes poorly again — because during standing, walking, sitting, lying down, and daily activity, awareness wasn't sustained, so merit stopped flowing through. Every moment, some energy flows through us; when merit isn't what flows through, something neutral or unwholesome flows through instead — and that shows up as a poorer sit the next time.
So the two must be trained together — awareness during activity (standing, walking, sitting, lying down) alongside sitting meditation, alternating, never leaving a gap without awareness. Sitting meditation is awareness during sitting; awareness in every other posture is awareness too, both needed so that the thread of knowing, the thread of mindfulness, stays unbroken and keeps drawing pure energy in. Once that pure energy arises, it drives the wholesome system, refining the elements within us toward ever greater purity, bringing about purity and release again and again. As long as we stay within that wholesome system — aware always, never lapsing — our life becomes one of purity and release, whether our eyes are open or closed.
