108 breaths. Not more, not less. That sounds simple. And that is exactly the point. Sûsokukan 数息観 — the breath-counting meditation of Shingon Buddhism — is one of the most fundamental and at the same time most powerful practices in the Japanese meditation tradition. No visualisation, no mantra, no complex ritual. Just you, your breath and the number. And still, this practice changes something fundamental.

Anyone who has ever tried to stay with 108 breaths really attentively knows: the mind has other plans. It jumps. It comments. It invents stories. Sûsokukan shows you that — not as theory, but as direct experience. And that is exactly why this practice has been the entry point into all the deeper meditations of Shingon for centuries.

What is Sûsokukan? 数息観

数息観
数 — to count. Soku 息 — breath. Kan 観 — observation, contemplation. Literally: "breath-counting contemplation." A meditation practice in which breaths are counted to gather the mind and bring it to a single point.

Sûsokukan is not an invention of any modern mindfulness movement. Its roots reach deep into the Buddhist tradition of East Asia — and in Shingon Buddhism it serves as the basic preparation for all deeper practices. Before a practitioner works with mantra, mudra and Siddham visualisation, they must stabilise the mind. Sûsokukan is the foundation on which everything else stands.

The principle is clear: you sit upright, breathe consciously and count each breath. In cycles of nine. One to nine, then again from the beginning — until you reach 108 breaths. Sounds simple. It is. And still you will notice that your mind drifts off after the third breath. That is exactly where the actual practice begins: the noticing. The returning. The starting again. Not as failure — but as the core of what meditation means.

The foundations of the practice

The sitting posture is the first decision. Upright, stable, dignified. Whether cross-legged on a cushion, in seiza on your knees, or on a chair — what matters is the straight spine. The chin is slightly tucked in, as if an invisible thread were pulling the crown to the ceiling. The shoulders drop in relaxation. The eyes are slightly open or closed — in Shingon, both traditions exist.

The hands form a mudra. In the simplest variant they rest in the lap, one on top of the other — the right hand in the left, the tips of the thumbs touching gently. This gesture is called Hokkai Jōin 法界定印 — the Dharmadhātu-Samādhi mudra. It signals to body and mind: now something different begins. Now there is no planning, no analysing, no reacting. Now there is only breathing.

The breath itself follows a natural rhythm. Inhale through the nose, deep into the belly. Exhale through the mouth, slowly and fully. Belly breathing — not chest breathing. The belly expands gently with the inhale and draws back with the exhale. No pressing, no forcing. The breath is allowed to flow. You observe it, count it, and let it happen at the same time.

The basic form

Sit upright. Hands in the lap. Inhale through the nose, exhale through the mouth. Count each breath — from one to nine, then start over. When you lose the thread, you begin again at one. In this way you count 108 breaths altogether. That is Sûsokukan in its simplest form — and it is enough to change the mind.

The cycles of nine have a good reason. Nine is a manageable unit. It gives the mind a frame without overwhelming it. Anyone who tries to count straight to 108 often gets lost in thoughts at twenty and does not notice it. The cycles of nine, by contrast, offer regular checkpoints: every time you reach nine, you know — I really was here just now.

108 — why this number? 百八

The number 108 is one of the most sacred numbers in Buddhism. If you visit a temple in Japan at New Year, you hear 108 strikes of the bell — Joya no Kane 除夜の鐘. Each strike stands for one of the 108 Bonnō 煩悩 — passions, delusions, inner obstacles that cloud the mind. With each strike, one delusion dissolves. When the last sound fades, the new year begins with a clear mind.

The Buddhist prayer beads — the mala 数珠 — have 108 beads. Each bead is counted between the fingers during the recitation of a mantra. In the Shingon tradition the mala is a ritual tool that guides the practitioner through repetition until the mind becomes still on its own. 108 mantras. 108 breaths. 108 bell strikes. The number returns again and again — as the measure of a complete practice.

Where exactly the 108 comes from is explained in many ways within the Buddhist tradition. One common derivation: six senses (seeing, hearing, smelling, tasting, touching, thinking), multiplied by three time-frames (past, present, future), multiplied by two qualities (pleasant, unpleasant), multiplied by three states (clinging, aversion, ignorance). 6 x 3 x 2 x 3 = 108. Each Bonnō a knot in the net of delusion. The practice of 108 breaths cuts through this net — not through battle, but through quiet attention.

"108 breaths are not a fitness test for the mind. It is an encounter. You meet everything that normally steers you — and you stay seated anyway. That is the beginning of freedom." Dr. Mark Hosak

Sûsokukan as entry — and what comes after

Sûsokukan is a gateway. It is consciously designed as the entry — as the practice with which everything begins. In the temples of Shingon Buddhism it is taught to novices first. Not because it would be unimportant, but because without it nothing further works. Anyone who cannot hold their mind for 108 breaths will not get very far with mantra recitation, Siddham visualisation or ritual meditation. Focus is the foundation.

That is why Sûsokukan is also of central importance in Shingon Reiki practice. It prepares the mind for the Moon Disc Meditation (Gachirinkan), for the work with mantra and mudra, for the deeper layers of energy practice. Anyone who practices Sûsokukan regularly notices: thoughts grow quieter. Perception becomes finer. The capacity to stay with one thing grows.

And here lies the decisive point: the foundations of Sûsokukan — sitting, breathing, counting — can be started by anyone immediately. No initiation, no ritual, no secret is needed for that. Only the decision to sit down. But the deeper practices that build on this foundation — the visualisations, the mantra work, the integration into the Shingon system — those are layers that become accessible through initiation and transmission. That is how it has always been in this tradition. The foundation is open. The depth is passed on.

If you are just beginning, ten minutes a day are enough. Sit down, form the mudra, begin to count. The first times you will hardly reach ten without drifting off. That is normal. Every return to the count is a moment of clarity — not failure, but practice. After a few weeks you will notice how not only the meditation changes, but your everyday life as well. The capacity to be present transfers to everything.

The inner resistances that arise during practice — restlessness, boredom, sudden tiredness, the urge to get up — are not disturbances. They are part of the 108 Bonnō. Every breath you count anyway is a quiet act of clearing. Not against these states, but through them.

The path

Sûsokukan is the foundation. Anyone who takes root here finds the deeper practices of Shingon opening on their own. Not as a technique you read up on — but as a living transmission passed down in an unbroken lineage for over 1200 years.
