Book excerpt: The second half of life--which we can enter at any age--is that time when we begin the process essential to a mature faith: discovering who we are, exploring our relationship with God, and beginning to let go. This part of life has a depth and spirituality all its own--a need for structure and rule, a tolerance of ambiguity, an exploration of limitation and mortality, and the deep work of discipline and detachment. Margaret Guenther brings her insights as a spiritual director to the gifts and opportunities of those of us who are on this journey to "holy ground." In each chapter, Toward Holy Ground explores the practical aspects of spirituality in midlife: intercessory prayer, a sense of community, a rule of life, lightheartedness, detachment, and stripping down, preparing for "a good death." A final chapter discusses practical aspects of ministry to the frail aged.
