When we are stressed, uncomfortable, lazy, or having unclear thoughts, we can concentrate on the central channel and use the breath to come down the two side channels, and up through the central channel out the mouth or crown of the head. Not forcefully like “Phet!” but in a relaxed way. Feel the breath coming up through the central channel and out the crown of the head, seven or fourteen times. Without any effort this wind naturally becomes a blissful wind, and makes our mind clear, pure, fresh, and comfortable.
