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.
Holy listening, to "listen" another's soul into life, into a condition of disclosure and discovery, may be almost the greatest service that any human being ever performs for another (or oneself).
