Silence
Silence is also speech.
Listen, listen, listen! All that you will ever need to know is already within you awaiting your inner ear. If you seek to understand your past, the answer is within you. If you need direction for today, the answer is within you. You do not have to seek "out there" for answers to your future. It is already within you awaiting your asking. You do not have to go here or there to find Go or the answer to your simplest or highest question. All you must do is be still and listen to the inner still small voice that forever sings the true song.
