Ascent of Mount Carmel

Ascent of Mount Carmel (Spanish: Subida del Monte Carmelo) is a 16th-century spiritual treatise by Spanish Catholic mystic and poet Saint John of the Cross. The book is a systematic treatment of the ascetical life in pursuit of mystical union with Christ, giving advice and reporting on his own experience. Alongside another connected work by John, entitled The Dark Night, it details the so-called Dark Night of the Soul, when the individual Soul undergoes earthly and spiritual privations in search of union with God. These two works, together with John's The Living Flame of Love and the Spiritual Canticle, are regarded as some of the greatest works both in Christian mysticism and in the Spanish language.
Written between 1578 and 1579 in Granada, Spain, after his escape from prison, the Ascent is illustrated by a diagram of the process outlined in the text of the Soul's progress to the summit of the metaphorical Mount Carmel where God is encountered. The work is divided into three sections and is set out as a commentary on four poetic stanzas by John on the subject of the Dark Night. John shows how the Soul sets out to leave all worldly ties and appetites behind to achieve "nothing less than transformation in God". (wikipedia.org)
