“Keeping external sense objects outside, fixing the gaze between the eyebrows, equalising the incoming and outgoing breaths within the nostrils —”
Verses 5.27-28 together describe the meditative posture of the Sage who is approaching liberation. External objects are shut out through withdrawal of the senses (pratyahara). The gaze is directed inward at the ajna chakra (between the eyebrows). The breath is balanced through pranayama. These are not ends in themselves but preparations for the culminating knowledge described in verse 5.29.
This verse gives a concrete meditation technique: sit still, close your eyes, gently direct your inner gaze upward to the point between the eyebrows, and focus on the natural rhythm of your breath entering and leaving the nostrils. Even five minutes of this practice can significantly settle the mind.
