We need silence to be able to touch souls. The more we receive in silent prayer, the more we can give in our active life. God is a friend of silence. The essential thing is not what we say, but what God will say through us.
This was my first conscious experience of listening to Gaia, even though I didn't call it that then or hear an actual voice... I have come to learn that there are many ways of listening. One may hear an internal or external voice, feel a body sensation, or simply just "know" with that intuitive understanding that is beyond words. However, I continue to describe this experience as "listening" because we have forgotten how to be silent and listen to ourselves, one another, and the earth.
