This article examines tristhana, the three places of attention that give Ashtanga Vinyasa its meditative character: the posture, the breath, and the gazing point. It explains each in turn, shows how holding all three together transforms a physical routine into a moving meditation, offers practical guidance for a beginner learning to coordinate them, and closes with a careful reading of what current research does and does not support about the breath and the gaze.
Three things at once
In the first article I said that Ashtanga is not a gentle drift through a few stretches, and that its structure is the thing that carries you. Tristhana is where that structure lives. The word means three places, and it points to the three things a practitioner is asked to hold together in every posture: the posture itself, the breath, and the point where the eyes rest.
This sounds simple until you try it. Most of us can manage one of the three. We can hold a shape, or we can breathe slowly, or we can fix our gaze. Holding all three at the same time is another matter, and it is precisely that difficulty that does the work. When the body, breath, and eyes are gathered around the same act, the mind is given fewer openings through which to wander. What began as exercise quietly becomes meditation.
The tradition describes tristhana as purifying three things in turn: the body through posture, the nervous system through breath, and the mind through the gaze. Whether or not one takes that account literally, it is a useful way to remember that each of the three is doing something distinct.
The posture
The first place is asana, the posture. Within tristhana, asana is less about achieving a picture-perfect shape and more about finding a seat that is both steady and workable, so that attention has somewhere stable to live. In the flowing sequences of Ashtanga, each posture is a station the breath passes through, not a pose to be frozen and admired.
I will give asana its own fuller treatment when we reach the sun salutations and the Primary Series. For now it is enough to see its role here: the posture is the ground on which the other two, breath and gaze, do their finer work.
The breath
The second place is the breath, and in contemporary Ashtanga teaching it is often described as ujjayi. Some teachers within the Jois lineage prefer the expression "free breathing with sound," distinguishing the breath used during asana from formal ujjayi pranayama. In either description, the breath remains nasal, continuous, audible to the practitioner, and free from retention or force, with only a light narrowing of the throat that gives it a soft, steady, ocean-like sound. That sound is not decoration. It gives the breath something the ear can track, so that lengthening or shortening becomes audible, and any ragged patch in the practice announces itself at once.
The breath is also what leads the movement. In Ashtanga you do not move and then breathe; you let each inhalation or exhalation carry you into the next position. This is what makes the practice one continuous motion rather than a string of separate poses. When the breath is calm and even, the practice is calm and even, however hard the body is working. When the breath frays, that is your signal to ease off, not to push harder.
A caution worth stating plainly: many teachers ask beginners to learn the smooth rhythm of the breath first and add the ujjayi sound gently, without forcing or straining the throat. The point is a long, even breath, not a loud one.
The gaze
The third place is drishti, the gazing point. In each posture the eyes are directed, with a soft focus, toward one of a set of specific points: the tip of the nose, the space between the brows, the navel, the hand, the toes, or off to one side. The gaze is steady but never strained, more a resting of the eyes than a stare.
The logic here is one every practitioner recognises. Where the eyes go, the attention follows. Left free, the eyes drift to the clock, to the person on the next mat, to the flaking skin on your own foot, and the mind drifts with them. By giving the eyes a single place to rest, drishti quietly removes one of the mind's favourite exits. In this it works hand in hand with the fifth and sixth limbs of Patanjali's path, the withdrawal of the senses and concentration, which the companion series explores in depth.
How the three become one
The real teaching of tristhana is not in any of the three parts alone but in their meeting. A steady posture without breath becomes rigid. Breath without a gaze leaves the eyes and the mind to wander. A gaze without breath becomes a hard stare. Braided together, they hold attention from three directions at once, and in that triple hold the ordinary chatter of the mind finds little space to continue.
This is why experienced practitioners often describe an Ashtanga practice as meditative despite its physical intensity. The meditation is not something added at the end. It is built into the method, produced by the simple, demanding act of keeping three things together while the body moves.
Learning it as a beginner
If you are new to this, begin with the breath and a short, manageable sequence. Learn how inhalation and exhalation accompany the movements without forcing their length or sound. As the basic sequence becomes familiar, add the prescribed drishti and gradually refine the postures. The three develop together, but the breath should remain the thread that prevents the physical form from becoming the sole objective.
Expect to lose two of the three constantly in the beginning. You will hold the posture and forget to breathe, or breathe beautifully and find your eyes wandering. That is normal, and noticing it is itself the practice. Each time you gather the three back together, you are training exactly the attention the whole system is designed to build.
What the research says
Because tristhana rests on breath and gaze, the relevant evidence comes mostly from research on slow breathing and on visual attention, and it deserves an honest reading.
On the breath, controlled studies of yogic slow breathing are among the more informative in the field, though they must be read with care. Work with a small group of yoga-naive participants found that slowing the breath to roughly five or six cycles a minute can raise baroreflex sensitivity, a marker of healthy cardiovascular control, improve oxygen saturation, and lower blood pressure. What is interesting for Ashtanga is a subtler finding from the same line of research: the ujjayi throat constriction did not clearly outperform plain slow breathing, and in some measures it helped slightly less, because the added resistance demands more effort.
An important limitation must be stated, however. These experiments examined brief, controlled breathing while participants were lying down, not breathing during a vigorous Ashtanga sequence. Their findings therefore cannot be transferred directly to practice on the mat. Within Ashtanga practice, the audible quality of the breath may still function as a practical form of pacing and feedback, although this particular role has not been tested directly. A separate small exploratory study in individuals with spinal cord injury suggested ujjayi may aid oxygen saturation and some measures of ventilatory efficiency, but with only twelve participants, all with spinal cord injury, those results are preliminary and cannot be generalised to healthy practitioners.
On the gaze, the ground is softer. Cognitive research shows that patterns of eye movement and mind-wandering are related, although the relationship varies with the task. This makes drishti a plausible attentional aid, but it does not by itself prove that a yogic fixed gaze reduces mind-wandering. Several of the stronger claims one meets online, about specific brain networks or reflexes, rest on general attention research or on tradition rather than on studies of the yogic practice as such. The sensible position is that drishti is a plausible and time-tested attentional aid, consistent with what we know about vision and focus, and not something that has been separately proven in the laboratory.
As before, I would rather understate this than oversell it. The value of tristhana does not depend on a research paper. It is something you can verify for yourself on the mat, in the difference between a distracted practice and one where breath, gaze, and posture are held as one.
Closing
Tristhana is the quiet engine of Ashtanga Vinyasa. Learn to hold its three points together and you have the whole method in miniature, a way of gathering body, breath, and attention into a single moving act. In the next article we will look closely at the breath alone, at how the ujjayi rhythm is built and how it carries the practice.
For now, on your next practice, try holding just two of the three, the breath and the gaze, and watch how much steadier the mind becomes.

Note on the gaze: Claims regarding drishti draw on the broader cognitive-science literature on visual fixation and sustained attention rather than on trials of the yogic practice itself, which remain limited. The Yoga Sutras provide the broader framework of concentration, while more explicit instructions involving the direction or fixing of the gaze appear in texts such as the Bhagavad Gita and the Hatha Yoga Pradipika.
