``It is not happiness that makes us grateful, but gratefulness that makes us happy.`` Through his books and appearances, David Steindl-Rast has shared the blessings of the thankful heart with millions. With this uncommon journal, he invites us to find greater depth and joy amid our daily challenges and burdens. These visually inspiring pages invite us to spark our own thankfulness when feeling weary or numb, transform our ``dismissible`` moments into fresh delights, dance with both the light and dark we encounter, and merge with the stream of the natural world. ``The mystic is not a special kind of human being,`` writes Brother David, ``rather, every human being is a special kind of mystic.`` No matter how ordinary we might feel, May Cause Happiness is sure to do just that, as it opens portals to the extraordinary within and all around us to be revisited again and again.
