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.
To begin to enter into the profound silence that resides in the depths of our beings is to begin to enter the realm of the Godhead beyond God. Beyond speech, beyond apprehension, is a realm of generative actuality, the realm of essential being out of which the Word is eternally begotten. Our silence is both and the clear road by which the Word proceeds most directly into our hearts.
For the abbas (fathers) and ammas (mothers) of the desert, solitude with its silence was a creative medium, a forge of transformation through which the false self in its adaptation to the pride, luxury, lust for power, and greed of the "world" was melted away in the fires of spiritual discernment. One emerged from the silence as a transformed self ... a person of humility, compassion, and responsiveness to the Word of God.
Silence was much more than not speaking, it was mostly a quality of heart. It was the creation of an inner space where genuine listening takes place. The ammas and abbas knew that in silence the Word most readily takes root.
