We cannot expect answers from God after only five minutes of silence... Meister Eckhart emphasized the importance of the listening heart that listens to God alone ... that God desires nothing more than a heart that detaches itself in silence from everything and turns and listens.
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.
