One of the central themes of the book, Bahá’u’lláh indicates, is that of “transformation”, meaning here the return of the Promised One in a different human guise. Indeed, in a prefatory note written above the opening lines of the original manuscript, Bahá’u’lláh states: This treatise was written in reply to a seeker who had asked how the promised Mihdí could have become transformed into ‘Alí-Muḥammad (the Báb). The opportunity provided by this question was seized to elaborate on a number of subjects, all of which are of use and benefit both to them that seek and to those who have attained, could ye perceive with the eye of divine virtue. The seeker alluded to in the above passage was Siyyid Yúsuf-i-Sihdihí Iṣfáhání, who at the time was residing in Karbilá. His questions were presented to Bahá’u’lláh through an intermediary, and this Tablet was revealed in response on the same day. A number of other important themes are addressed in this work as well: the cause of the rejection of the Prophets of the past; the danger of a literal reading of scripture; the meaning of the signs and portents of the Bible concerning the advent of the new Manifestation; the continuity of divine revelation; intimations of Bahá’u’lláh’s own approaching declaration; the significance of such symbolic terms as “the Day of Judgement”, “the Resurrection”, “attainment to the Divine Presence”, and “life and death”; and the stages of the spiritual quest through “the Garden of Search”, “the City of Love and Rapture”, “the City of Divine Unity”, “the Garden of Wonderment”, “the City of Absolute Nothingness”, “the City of Immortality”, and “the City that hath no name or description”. The publication of Gems of Divine Mysteries is one of the projects undertaken in fulfilment of the Five Year Plan goal, announced in April 2001, of “enriching the translations into English from the Holy Texts”. The volume will further deepen the Western reader’s appreciation of a period infused with potentiality and described by Shoghi Effendi as “the vernal years of Bahá’u’lláh’s ministry”, and assist the students of His Revelation in gaining a more profound insight into its gradual unfoldment. GEMS OF DIVINE MYSTERY The essence of the divine mysteries in the journeys of ascent set forth for those who long to draw nigh unto God, the Almighty, the Ever-Forgiving—blessed be the righteous that quaff from these crystal streams! HE IS THE EXALTED, THE MOST HIGH!
