Fleet Maull is an acharya—or senior mindfulness meditation teacher—in the Shambhala International Meditation Community. In 1989, Fleet founded the Prison Dharma Network—now called The Prison Mindfulness Institute—while serving a federal prison sentence. He is the author of the book Dharma in Hell: The Prison Writings of Fleet Maull and has founded several prisoner advocacy organizations. In this fascinating edition of Insights at the Edge, Fleet and Tami Simon discuss practices for dealing with regret and what it means to truly devote ourselves to the service of others. They also speak on Buddhist views of basic human goodness and how they helped Fleet to come to terms with his prison experience. Finally, Fleet talks about his vision for the reform of the American criminal justice system and the slow growth toward a more enlightened society. (72 minutes)
