A few years ago, during the BBC TV programme, ‘The Monastery’, based on Worth Abbey in Sussex, one of the monks was showing a group of school children around. Standing with them in the quiet chapel he stilled the children’s chatter: ‘Shush ! Can you hear that?’ he said. There was not a sound to be heard yet he continued: ‘Do you know what that is ? It’s called ‘silence’! He went on to explain to his young visitors what discoveries can be made when we open ourselves to the wonderful world of silence, with all its possibilities.
