When we don't listen, we are shutting ourselves off -- not from others but from ourselves. We can't do anything from a place of knowing. When we think we know something, we don't listen. We have to empty ourselves over and over, return to unknowing, and just listen. And listen. And listen... And once we listen, we have to act. The functioning that comes out of listening -- out of "Attention!" -- is compassionate action. If we don't listen, we can't act with compassion.
To open to the sense, to become really conscious, you have to drop out of the future and the past and remain for a time in what T. S. Eliot called "the still point of the turning world" — the present. The only true reality is the present.
