Deep Concentration in Meditation and Daily Life, Explained

Deep concentration, as Shinzen Young presents it, is not a feat of willpower but a trainable state that sits between two familiar extremes: the wired alertness of a busy day and the blank rest of sleep. In a 2010 Google Tech Talk, Young walks a room of listeners through a short guided sitting, then explains why a small, almost invisible exercise in noticing relaxation can, over years, change how a person attends to everything else. The core technique is a mental label, "feel rest," applied to the muscles of the body. The theory behind it draws on posture and the nervous system, on the difference between narrowing and tightening attention, and on the claim that concentration is a skill that compounds with practice. What follows unpacks those ideas for readers who were not in the room.

What does "feel rest" actually ask you to do?

The session opened with a framing Young offered as both practice and theory. Most people's waking state, he said, is alert but frenetic, and most people's sleep is restful but gives up alertness entirely. Meditation, in his description, aims to keep both at once. "What meditation is simply the best of both worlds simultaneously," he told the audience (Google Tech Talk, 2010, at 0:00 onward).

The practical instrument is a label. Young uses the word "feel" to mean anything in the body, and "rest" to mean something deliberately modest: muscle relaxation, or the settling of the body into its posture. When you notice that settling, you say "feel rest" mentally, every few seconds, to keep your attention anchored to it. He was specific about where relaxation can show up. You might feel it in one place, move from place to place, or sense it "simultaneously and uniformly throughout your body." Each of those is fine. The objective is not a particular sensation but the act of returning to the pleasant quality of muscles letting go.

Young explained the physiology he wanted his listeners to notice. Each out-breath, the intercostal muscles and the diaphragm relax on their own; the exhale is driven by the elasticity stored in the tissue plus gravity. "So the out breath, all muscles have to do essentially for an out-breath is relax," he said. A practitioner who tunes into the core of the body can find that flavor of relaxation arriving on every exhale without effort. The label simply gives attention something to hold.

Why does posture decide how awake you are?

Young's first instruction was about the spine, and he gave it a physiological reason. Posture and alertness are linked, he said, through the reticular activating system in the central nervous system. When the upper body wilts, that system quiets, the brain processes less, and in the extreme a person becomes drowsy. Keep the spine straight, and the brain is physiologically woken up. The trick, he said, is balance (Google Tech Talk, 2010, at 4:14): "You learn how to align your spine and then just let the whole body just hang from that."

That combination is harder than it sounds, and Young was candid about it. Many newcomers assume an upright spine must mean a tense body. To support his point that the two can coexist, he cited electromyographic studies of Zen monks in Japan, which monitored the electrical activity of their postural muscles in real time. The monks could hold a bolt-upright posture for hours, and their muscles were more relaxed than they would have been lying horizontal and asleep. Young was clear that this capacity takes years to develop. For beginners, the practical lesson is a motor skill: align the spine, then let the body settle into the alignment rather than collapsing out of it.

Is concentration a narrowing of attention, or something else?

The most useful conceptual move in the talk is Young's description of what the exercise actually trains. He called it "an exercise in selective attention." During the sitting, the room was asked to notice that inner talk, mental images, body discomfort, impatience, sleepiness, and external sounds would all arise, and that none of this was a failure. "Perfectly okay, totally give permission for all that to activate," he said. The only thing to do is return, gently, to the relaxation each time you are caught by something else. Mental talk gets a gentle return. Mental images of the past, the future, or fantasy get the same. So do sensations of discomfort.

The subtlety of the target is deliberate. Relaxation, he noted, can be very mild compared to the intensity of what is competing for attention. He compared it to a familiar act of listening: "Like when you listen for a faint sound, you get very concentrated." If the relaxation is only subtle, you have to be very highly focused, and that effort is what builds concentration. Young also addressed a common misunderstanding that surfaced in discussion. Concentration is a narrowing of attention, but narrowing is not the whole story. In his framing, the goal is a quality of focus that stays steady while the mind's content keeps changing, which is why the same skill can be carried into ordinary activity such as driving, where sounds and body sensations are what matter in the moment (Google Tech Talk, 2010, at 48:48 onward).

Can concentration be trained like a skill, or does it just happen?

Young insisted it is a trained skill, and in the question period he drew a sharp line between active practice and passive experience. Asked whether gaming or screen time could build the same capacities, he offered a metaphor: passive exercise. "If I grab your hand and raise it," he said, the arm moves, but the arm has not acquired strength or coordination through the lift. The same logic, in his view, applies to watching television or playing video games. Stimulation is not the same as training. Building skill, he argued, requires "a disciplined technique."

That distinction is the practical heart of the talk. Concentration does not come from intensity alone, or from being entertained or absorbed. It comes from repeatedly choosing one object of attention, noticing the drift, and returning. The exercise is small enough to fit into a few minutes, which is part of its design. Young pointed to the arithmetic of routine: a person who practices formally for ten minutes a day, he said, will feel the effects differently across months, years and decades of sustained practice.

What changes after decades of practice?

The most striking claim in the session concerns compounding. Young described the growth of meditative ability as close to exponential, a dynamic he framed as "the proverbial positive feedback loop." The more concentration you develop, the easier it becomes to develop more, because a steadier mind makes each subsequent sitting more productive. He reported his own experience in these terms, saying that he felt he was in a very deep meditative state even while giving the talk itself. Readers should weigh that as one teacher's testimony rather than a measured result, but it captures the logic he was describing: a skill that improves the conditions for its own improvement.

Young also positioned concentration as foundational to everything else. In a discussion of how knowledge is built, he placed what he called the most basic human trainable skill at the base of a pyramid of capacities, the layer on which the others rest. That framing made the modest exercise of the first few minutes look less like a warm-up and more like the groundwork for everything the audience would later try to learn.

Why did a room of technologists need this?

The setting matters. A Google Tech Talk audience is accustomed to tools that demand attention and reward distraction. Young's argument is not anti-technology, but it is pointed about attention as a trainable faculty rather than a fixed trait. The practical takeaway he left is intentionally plain. Sit upright with the body relaxed. Choose a subtle object of attention, such as the feeling of muscles letting go, and label it. When you are caught in talk, images, or discomfort, return. Do it for a short period each day, and do it for years. The rest, in his account, follows from the skill itself.

Where to go from here

Start with the exercise as Young describes it. Sit with the spine straight and let the body hang from that alignment. Use the label "feel rest" every few seconds, and keep the target subtle. Treat each return from distraction as the repetition that builds the skill, not as a failure. For a full picture, watch the complete 2010 Google Tech Talk, where Young takes questions on gaming, television, and the long-term trajectory of practice. Keep the distinction he drew between passive stimulation and disciplined technique in mind as you judge your own progress: the goal is not to be stirred by what you do, but to become steadier at choosing where your attention goes.
