In this sweeping exploration of mystical spirituality, theologian Lanzetta (The Monk Within) invites readers to live as “monks in the world.” She recommends turning away from the ambition and complexity of “secular culture” and instead opting for the simplicity of the “inner monastic” life while remaining committed to one’s obligations as a friend, family member, employee, or student. Lanzetta weaves various traditions and offers a “kaleidoscope”of contemplations on the spiritual life, quoting Rumi on compassion (“The spirit became joyful through the I-less I; it fled from the I of the world”), Gandhi on nonviolence, and Indigenous elders on humility and simplicity (such as the Seven Grandfather Teaching of the Potawatomi Nation: “You cannot have Wisdom without Love, Respect, Bravery, Honesty, Humility, and Truth”). She also provides practical exercises to foster a more contemplative presence in the world, including a host of meditation practices, tips for prayerful imagination, and altar-building ideas for constructing an “inner monastery” in one’s home. Written for the “spiritual, but not religious,” this will appeal to anyone looking for mystical experiences in the midst of the mundane. (Self-published)
