The Magus of Strovolos: The Extraordinary World of a Spiritual Healer is a 1985 book that was written by Kyriacos C. Markides.
 It is the first book of a trilogy about Stylianos Atteshlis, a 20th-century Christian mystic and healer who lived in the town of Strovolos, Cyprus.
Gina Cerminara (April 11, 1914 – April 1984) was an American author in the fields of parapsychology, spirituality and reincarnation.
 She was born in Milwaukee and received BA, MA, and Ph.D. degrees in psychology from the University of Wisconsin–Madison.
 Her years of research regarding Edgar Cayce led her to publish a book about reincarnation in 1950 titled "Many Mansions".
 Her other books on reincarnation include "The World Within", "Many Lives, Many Loves" and "Insights for the Age of Aquarius".
Jakob Böhme ( ; 1575 – 17 November 1624) was a German Christian mystic and theologian.
 He was considered an original thinker by many of his contemporaries within the Lutheran tradition, and his first book, commonly known as "Aurora", caused a great scandal.
 In contemporary English, his name may be spelled Jacob Boehme; in seventeenth-century England it was also spelled Behmen, approximating the contemporary English pronunciation of the German "Böhme".
Agnes Blannbekin ( or ; c. 1244 – March 10, 1315), was an Austrian Beguine and Christian mystic.
 She was also referred to as "Saint Agnes Blannbekin" or the "Venerable Agnes Blannbekin", though never beatified or canonized by the Roman Catholic Church.
 Her controversial revelations were compiled by her confessor Ermenrich and later published in 1731 as "Venerabilis Agnetis Blannbekin".
 The copies were confiscated by the Society of Jesus, and only two manuscripts survived.
 One was destroyed in a fire at the Strasbourg library in 1870.
 The surviving manuscript, currently owned by a Cistercian convent in Zwettl, Austria, was not released until the 20th century.
 Although Blannbekin is best remembered today for her visions, during her life she was known for her ministry to the urban population.
Julian of Norwich (c. 8 November 1342 – c. 1416) was an English anchoress and an important Christian mystic and theologian.
 Her "Revelations of Divine Love", written around 1395, is the first book in the English language known to have been written by a woman.
 Julian was also known as a spiritual authority within her community, where she also served as a counsellor and advisor.
 She is venerated in the Anglican and Lutheran churches.
 The Roman Catholic Church has not declared her to be a saint or given her the title Blessed.
 Accordingly, she does not appear in the "Roman Martyrology", nor is she included in the calendar of the Catholic Church in England and Wales.
Edgar Cayce ( ; March 18, 1877 – January 3, 1945) was an American Christian mystic who answered questions on subjects as varied as healing, reincarnation, wars, Atlantis, and future events while claiming to be in a trance.
 A biographer gave him the nickname, "The Sleeping Prophet".
 A nonprofit organization, the Association for Research and Enlightenment,<ref name='ARE About/Mission'> </ref> was founded to facilitate the study of Cayce's work.
Corinne Heline (August 18, 1882 in Atlanta, Georgia – July 26, 1975) was an American author, Christian mystic, and occultist who published 28 books.
Flower Arlene Newhouse (May 10, 1909 – July 8, 1994) was an American Christian mystic and spiritual teacher.
The Book of Margery Kempe is a medieval text attributed to Margery Kempe, an English Christian mystic and pilgrim who lived at the turn of the fifteenth century.
 It details Kempe's life, her travels, her alleged experiences of divine revelation (including her visions of interacting with Jesus as well as other biblical figures), and her presence at key biblical events such as the Nativity and the Crucifixion.
Margery Kempe (c. 1373–after 1438) was an English Christian mystic, known for writing through dictation "The Book of Margery Kempe", a work considered by some to be the first autobiography in the English language.
 Her book chronicles her domestic tribulations, her extensive pilgrimages to holy sites in Europe and the Holy Land, as well as her mystical conversations with God.
 She is honoured in the Anglican Communion, but was never made a Roman Catholic saint.
