Context: Matthew Fox (born Timothy James Fox in 1940) is an American priest and theologian.  Formerly a member of the Dominican Order within the Roman Catholic Church, he became a member of the Episcopal Church following his expulsion from the order in 1993.  Fox was an early and influential exponent of a movement that came to be known as Creation Spirituality.  The movement draws inspiration from the mystical philosophies of such medieval Catholic visionaries as Hildegard of Bingen, Thomas Aquinas, Saint Francis of Assisi, Julian of Norwich, Dante Alighieri, Meister Eckhart and Nicholas of Cusa, as well as the wisdom and prophetic traditions of Jewish scriptures.  Creation Spirituality is also strongly aligned with ecological and environmental movements of the late 20th century and embraces numerous spiritual traditions around the world, including Buddhism, Judaism, Sufism, and Native American spirituality, with a focus on "deep ecumenism" or interfaith. Traditional healers of South Africa are practitioners of traditional African medicine in Southern Africa.  They fulfill different social and political roles in the community, including divination, healing physical, emotional and spiritual illnesses, directing birth or death rituals, finding lost cattle, protecting warriors, counteracting witchcraft, and narrating the history, cosmology, and myths of their tradition.  There are two main types of traditional healers within the Nguni, Sotho-Tswana, and Tsonga societies of Southern Africa: the diviner ("sangoma"), and the herbalist ("inyanga").  These healers are effectively South African shamans who are highly revered and respected in a society where illness is thought to be caused by witchcraft, pollution (contact with impure objects or occurrences) or through neglect of the ancestors.  It is estimated that there are as many as 200,000 indigenous traditional healers in South Africa compared to 25,000 Western-trained doctors.  Traditional healers are consulted by approximately 60% of the South African population, usually in conjunction with modern biomedical services. Choiceless awareness is posited in philosophy, psychology, and spirituality to be the state of unpremeditated, complete awareness of the present without preference, effort, or compulsion.  The term was popularized in mid-20th century by Jiddu Krishnamurti, in whose philosophy it signifies a main theme.  Similar or related concepts had been previously developed in several religious or spiritual traditions; the term or others like it has also been used to describe traditional and contemporary secular and religious meditation practices.  By choiceless awareness as a concept or term had appeared in a variety of fields, including in neuroscience, therapy, sociology, and in art.  However, Krishnamurti's approach of the subject was unique, and differs from both prior and later notions. Engaged Spirituality refers to religious or spiritual people who actively engage in the world in order to transform it in positive ways while finding nurturance, inspiration and guidance in their spiritual beliefs and practices.  The term was inspired by Engaged Buddhism a concept and set of values developed by the Vietnamese Buddhist monk Thich Nhat Hanh.  Engaged Spirituality encompasses people committed to social change from all the major faith traditions as well as people who refer to themselves as “spiritual but not religious.”  It has numerous iterations in practice yet common themes unite the many forms it takes.  For some in the Catholic tradition, Liberation Theology guides their form of engaged spirituality.
