Mindfulness is the practice that quiets the noise inside us. Without mindfulness, we can be pulled away by many things. Sometimes we are pulled away by regret and sorrow concerning the past. We revisit old memories and experiences, only to suffer again and again the pain we’ve already experienced. It’s easy to get caught in the prison of the past.
We may also get pulled away by the future. A person who is anxious and fearful about the future is trapped just as much as one bound by the past. Anxiety, fear, and uncertainty about future events prevent us from hearing the call of happiness. So the future becomes a kind of prison, too
