The mind of one who practises doesn't run away anywhere, it stays right there. Good, evil, happiness and unhappiness, right and wrong arise, and he knows them all. The meditator simply knows them, they don't enter his mind. That is, he has no clinging. He is simply the experiencer.
Ajahn ChahWhen we sit in meditation and hear a sound, we think, 'Oh, that sound's bothering me.' If we see it like this, we suffer. But if we investigate a little deeper, we see that the sound is simply sound. If we understand like this, then there's nothing more to it. We leave it be. The sound is just sound, why should you go and grab it? You see that actually it was you who went out and disturbed the sound.
