If you were only to listen, it becomes meditation. Without meditation you cannot hear. What is the meaning of meditation? Meditation exists only where mind is not; where the internal dialogue is gone.
No thought, no action, no movement, total stillness: only thus can one manifest the true nature and law of things from within and unconsciously, and at last become one with heaven and earth.
In the Buddha's life story we see the three stages of practice: Morality comes first, then concentrated meditation, and then wisdom. And we see that the path takes time.
