Practical Mysticism is a book written by Evelyn Underhill and first published in 1915. In this book Underhill sets out her belief that spiritual life is part of human nature and as such is available to every human being. Underhill's practical mysticism is secular rather than religious, since "it is a natural human activity

Science and religion have long been thought incompatible. But nowhere has this apparent contradiction been more fully resolved than in the figure of A. S. Eddington (1882-1944), a pioneer in astrophysics, relativity, and the popularization of science, and a devout Quaker. Practical Mystic uses the figure of Eddington to shows how religious and scientific values can interact and overlap without compromising the integrity of either. Eddington was a world-class scientist who not only maintained his religious belief throughout his scientific career but also defended the interrelation of science and religion while drawing inspiration from both for his practices. For instance, at a time when a strict adherence to deductive principles of physics had proved fruitless for understanding the nature of stars, insights from Quaker mysticism led Eddington to argue that an outlook less concerned with certainty and more concerned with further exploration was necessary to overcome the obstacles of incomplete and uncertain knowledge. By examining this intersection between liberal religion and astrophysics, Practical Mystic questions many common assumptions about the relationship between science and spirituality. Matthew Stanley's analysis of Eddington's personal convictions also reveals much about the practice, production, and dissemination of scientific knowledge at the beginning of the twentieth century.

Practical Mysticism in Islam and Christianity offers a comparative study of the works of the Sufi-poet Jalal al-Din Rumi (1207-1273) and the practical teachings of the German Dominican, Meister Eckhart (c1260-1327/8). Rumi has remained an influential figure in Islamic mystical discourse since the thirteenth century, while also extending his impact to the Western spiritual arena. However, his ideas have frequently been interpreted within the framework of other mystical, philosophical, or religious systems. Through its novel approach, this book aims to reformulate Rumi’s practical mysticism by employing four methodological principles: a) mysticism is a coherent structure with mutual interconnection between its parts; b) the imposition of alien structures to interpret any particular mysticism damages its inward coherency; c) practical mysticism consists of two main parts, namely practices and stages; and d) the proper use of comparative methodology enables a deeper understanding of each juxtaposed system. Eckhart’s speculative mysticism, which differs from and enjoys similarities with the love-based mysticism of Rumi, provides a "mirror" that highlights the special features of Rumi’s practical mysticism. Such comparison also allows a deeper comprehension of Eckhart’s practical thought. Offering a critical examination of practical mysticism, this book is a valuable resource for students and scholars of Islamic studies, comparative mysticism, and the intellectual history of Islam.

The Bahá'í Faith is a religion that was founded by Bahá'u'lláh in the mid-nineteenth century and has since spread all around the world. Though a way of life that is largely grounded in action, the mystical connection between the individual believer and God stands at its core. The seeker of truth aims to walk the mystical path with practical feet. This book highlights the place of mysticism in the Bahá'í Faith through an exploration of its sacred literature. It discusses Bahá'u'lláh’s teachings on God and creation, the purpose of life, the nature of spiritual experience and transformation, as well as the principles and practices that the spiritual seeker utilises on the path of transformation. Through this exploration we discover the potential of the human being to live an active and spiritual life in this world, drawing closer to God. Each person was created in the image of God and has the capacity to mirror all of God’s perfections, experiencing His light both in the outside world and within, in this world and the next.

Two classics in one volume that show a British poet and mystic to be one of the most authoritative modern voices on mysticism. "God gives without stint all that the creature needs, but it must do its part. He gives the wheat: we must reap and grind and bake it." –Evelyn Underhill Written on the eve of World War I, Practical Mysticism reviews the works of the greatest Western mystics, including Teresa of Avila, Julian of Norwich, and Thomas à Kempis. Underhill’s goal is to guide her readers on a journey toward mystical consciousness, to teach them to see the “eternal beauty beyond and beneath apparent ruthlessness.” Abba, first published in 1940, takes as its starting point the seven phrases of the Lord’s Prayer, using them as a means to propel the self toward union with God. In these important works, Underhill brings an often esoteric subject onto a practical footing, showing that the profound gifts of mysticism are not only for the few but are within reach of us all.
