"My good friend Brother Wayne Teasdale has long been actively involved in the effort to bring our religious traditions together. In this book Brother Wayne explores what he calls interspirituality. He shares his deep respect for and knowledge of the world’s religions, relates examples from the lives of many great spiritual practitioners, and illuminates the traditions’ wonderful commonalities. The Mystic Heart is a work of great inspiration.”
— His Holiness the Dalai Lama

“As a student of mysticism for more than thirty years, I have never encountered as thorough or profound a book as The Mystic Heart. Teasdale gives us a history, a multi-faith context, the actual experience of the mystical state, and a wide-ranging and practical set of how-to’s to bring the ancient secrets into the lives of modern mystics — like you and me.”
— Thom Hartmann, author of The Last Hours of Ancient Sunlight

“All the classical spiritual traditions are here! The Hindu and Buddhist, the Sufi, the Jewish, the Christian and Muslim, and the indigenous people, too — even the ecologists and their mystical sense of the natural world as divine manifestation. The Mystic Heart is a superb presentation of how these great spiritual traditions are now meeting and supporting each other — how they all give witness to the transforming presence of the divine in human consciousness. A dedicated scholar and practitioner, Wayne Teasdale adds to this personal insights drawn from a lifetime given to the study of the mystical traditions.”
— Thomas Berry, author of The Dream of the Earth

“With loving clarity and understanding of all genuine mystical experience from the great traditions, Brother Wayne Teasdale illuminates the ‘ecology of souls’ so that each of us, no matter what our path, can be attuned and enriched by the others. A fine masterwork by a living embodiment of the mystic heart.”
— Barbara Marx Hubbard, author of Conscious Evolution

“Those who share Teasdale’s optimistic vision of the coming age as fostering spiritual unity among diverse peoples will consider the book an inspirational guide.”
— Publishers Weekly

“This well-written and informative book will appeal both to scholars and informed lay readers. For academic libraries and public libraries with a strong religion collection.”
— Library Journal

“This is a landmark book in the field of interreligious dialogue, written with sensitivity and deep respect for all the great traditions.”
— The Hartford Courant

“The Mystic Heart is a beautiful and profound meditation on the commonalities at the core of the world's great religions. In this age of extreme pluralism, which encourages us to all be different (and fragmented), Brother Teasdale reminds us that Spirit is common in and to us all, and thus in addition to cherishing differences we can embrace unity. A wise and wonderful wake-up call to a world in shattered pieces.”
— Ken Wilber, author of The Marriage of Sense and Soul

“This rare and wonderful book awakens its readers to their own mystic nature. We discover here how previously divided and distinguished spiritual traditions are converging into a new river of holiness, an interspirituality. What is unique in this work is the luminous guidance the author gives us for deepening one’s personal faith while exploring the mystical genius of other traditions. It may well be, as Brother Teasdale so eloquently shows, that the mystical experience is perhaps the greatest accelerator of evolutionary enhancement. Through it, we tap into wider physical, mental, emotional and social systems and thus gain entrance into the next stage of our unfolding, both individually and collectively. Once the province of the few, the mystic path may now be the requirement of the many — a unique developmental path for self and world. The Mystic Heart goes to the heart of this matter.”
— Jean Houston, author of A Mythic Life

“The Mystic Heart is a visionary work that presents a bold and imaginative glimpse of the fruits of multifaith sharing and collaboration. Teasdale’s yearning for a universal communal spirituality that cuts across all traditions is one that we can celebrate. On these pages, he has presented stirring blueprints of global mysticism.”
— Spirituality & Health

“Teasdale's interspiritulity is more than just developing tolerance: it opens the door to even greater truths.”
— Personal Transformation

“Teasdale combines a Christian faith with an understanding of the world's religions, resulting in an excellent explanation of the principles and elements of universal spirituality.”
— The Bookwatch

“With a vast range of knowledge, Teasdale draws on the teachings, practices, and experiences of shamans, saints, and theologians of all ages and traditions, on his own experience, and on contemporary science, art, and poetry to provide an understanding of the goal of realizing ultimate reality as it appears under many names. . . . Hans Kung has said there will be no peace until there is understanding among world religions. This book is an informed and practical contribution to that understanding.”
—  CHOICE, Current Reviews for Academic Libraries

“The Mystic Heart reminds us that the fruits of our personal spiritual journey also have their own reward in giving to ourselves a greater capacity for openness and awareness, for spontaneity and joy, to be really present for others, in compassion and without expectation.”
— Conscious Choice

“The Mystic Heart is an excellent survey and overview of the present state of interfaith or multifaith spirituality at the end of the 20^th century.

“For [those] just beginning to wonder what we all have in common, where to look for the one God underneath all the rich religious diversity of the human family, this may be just the right guide.”
— National Catholic Reporter
