To live a surrendered life is to be present moment to moment with our experience, to accept our experience without judging it. Or if we judge it, to forgive ourselves for defending, for pushing away. To be with our experience does not mean that we do not space out, detach, disappear emotionally. It means that we become increasingly aware of when we dissociate and gently bring ourselves back. This "bringing ourselves back" is the essence of meditation. To meditate, it is not necessary to stop thinking. But it is necessary to become aware of the thoughts as they happen, to see how they take us out of the silence. To see how they prevent us from being wholly present.
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.
