Zazen posture and breath

Establish a stable, upright seated posture and let the breath settle as the ground of practice.

Why it works

Zen treats posture as primary, not incidental: a stable, upright, balanced position supports sustained alertness while reducing the physical fidgeting that fragments attention. A grounded posture and natural breathing also nudge the nervous system toward a calm-but-awake state, which is the physiological substrate the rest of the practice depends on.

How to do it

1. Sit on a cushion or chair with the spine upright but not rigid, hips slightly above the knees if on the floor.
2. Let the hands rest in a stable position and the eyes stay softly open, gaze lowered.
3. Let breathing be natural and settle into the belly; do not control it.
4. Hold the posture with relaxed steadiness, returning to it whenever you slump or stiffen.

Evidence

Posture and breath as the basis of meditation are consistent with general meditation research on attentional stability and calm arousal. The specific Zen postural forms are traditional conventions rather than independently optimized, studied variables. (mechanistic)

The general benefits of stable posture and calm breathing are supported; the precise Zen forms are tradition, not trial-derived.

Common mistake

Forcing a rigid, painful posture and treating endurance as the practice, which creates tension that pulls attention into the body’s complaints rather than steadying it.
