Book excerpt: A longing for purpose, happiness, and inner peace are rooted deeply in the soul of each of us. As we grow older, some might feel that these qualities are unattainable. Others feel complacent, often losing interest in things that once gave them pleasure and fulfilment, while others struggle with the inevitable changes in health and energy that are a natural part of life. In tough economic times, many people who had retired or who were close to retiring, realize they must still work. Mindfulness is a powerful practice that can alleviate stress and help people through all of life's ups and downs with more optimism and serenity.
