Letting the moment slip away. Of course, it would help if we became aware of the choice. Prisons are like up-market monasteries. Prisoners get three meals a day. Orthodox Buddhists get one every twenty four hours.
Prisoners sleep on beds, monks sleep on the floor.
In a fairly crowded and busy monastery, one of the great joys is to finish one's chores and slip into the solitary peacefulness of your own small room and meditate. In prison this is called 'solitary confinement'. What an opportunity to shut-up and listen. To 'shut-up' is to stop the endless flow of the hundreds and hundreds of words and thoughts that flow through your head every hour. Tune in to the present moment.
