Meditation clears the mind, inspires us, and makes possible appropriate action — action that is not emotional or ultimately destructive. This action may in effect be non-action: we may decide to let others make their own choices without interfering. However, such non-action, taken in the light of mindfulness, is a choice. It is not the case that we are afraid to act because of fear of conflict, or because we lack confidence.
Meditation and action go together: if we are in an abusive relationship, for example, meditation alone will not be enough to bring us peace. We need to take action. If we just sit and try to meditate in such a situation, a voice inside will be constantly reminding us that we need to do something. If we try to ignore that voice, it will talk louder. This is like our roommate calling from the other room. If we do not let him know that we heard, she will call louder. Peace of mind may come only when we listen to and acknowledge that inner voice, resolve to act on it, and then follow through.
Looking at meditation in this way may give you a different perspective on it. It may help you to see it as a proactive, instead of only a passive practice.
Mindfulness Coaching may help clarify your course of action.
