Krishna describes the physical posture for meditation. Body, head, and neck — all three aligned in one straight line. No leaning forward, no tilting back. No fidgeting. The gaze rests softly at the tip of the nose — eyes neither fully shut nor darting around.
Why such precise physical instructions? Because the body and mind mirror each other. When the body is restless, the mind follows. When the body is still, the mind has a chance to settle. Water in a bowl only becomes clear when the bowl stops shaking.
The nose-tip gaze is not about staring hard at one spot. It is a gentle anchoring of attention. When the eyes stop scanning the room, the mind stops scanning for distractions. The outer stillness creates a container for the inner work.
