Book excerpt: In the wise and often witty Forgetting Ourselves on Purpose, Brian Mahan considers the question of how it is possible to create a meaningful spiritual life while living in a culture that measures us by what we have rather than who we are. Drawing on nearly two decades of teaching experience. Brian Mahan shares stories of personal struggle and triumph that demonstrate how those who seek meaning and purpose have recalimed their authentic selves by resolving the inevitable tension between personal ambition and spiritual vibrancy.
