"We cannot find God in noise or agitation. Nature: trees, flowers, and grass grow in silence. The stars, the moon, and the sun move in silence. What is essential is not what we say, but what God tells us and what He tells others through us. In silence He listens to us; in silence He speaks to our souls. In silence, we are granted the privilege of listening to His voice.
Silence of our eyes.
Silence of our ears.
Silence of our mouths.
Silence of our minds.
...in the silence of the heart
God will speak.
Silence of the heart is necessary so you can hear God everywhere - in the closing of the door, in the person who needs you, in the birds that sing, in the flowers, in the animals.
If we are careful of silence, it will be easy to pray. There is so much talk, so much repetition, so much carrying on of tales in the words and in writing. (oops!) Our prayer life suffers so much because our hearts are not silent.
I shall keep the silence of my heart with greater care, so that in the silence of my heart I hear His words of comfort and from the fullness of my heart I comfort Jesus in the distressing disguise of the poor." ~Mother Teresa
