Interpretation

The classic description of meditation posture: the spine, neck, and head form one vertical line (samam — equal, aligned). The body is achalam (motionless) and sthira (steady). The gaze is directed at the tip of the nose — this is a focusing technique that draws the eyes' energy inward and prevents the mind from being pulled by visual distractions. Not looking in any direction means full withdrawal of the visual faculty from the external world. This outer stillness creates the conditions for inner stillness.
