Let him firmly hold his body, head and neck erect and still, gazing at the tip of his nose, without looking around.

Holding body, head and neck erect and still, steady, gazing at the tip of his own nose and not looking about in any direction,

Krishna turns to posture. Body, head and neck are held in a straight line, still and steady. The gaze rests on the tip of the nose, and the eyes do not wander in any direction. Commentators differ on whether this means literally looking at the nose or keeping the eyes half closed and directed downward, but the purpose is plain: to keep sight from pulling the mind outward. The verse begins a sentence that continues into the next, describing the meditator as a whole.
