In any activity that requires concentrated effort, the breath quite naturally plays a role. If you have ever tried to thread a needle or repair a watch, you might have observed that without even thinking about it the breath quiets and deepens. Singers, swimmers, people who struggle with panic attacks, and a host of others learn the importance of proper breathing in order to negotiate the respective tasks at hand. Thus, that the art of contemplative practice can be facilitated by the breath should come as no surprise.
In meditation we turn within a state of silent receptivity with that open inner eye of love, that listening ear, and we let our self unfold and reveal to us whatever is necessary to the NOW of our experience. We truly drink from the well of our consciousness. The water of eternal life "gushing up" brings forth to our external world a manifestation of harmony, love, peace and health.
