On occasion of Centenary of Bahá'u'lláh's release from oppressive imprisonment in the Siyáh-Chál, Tihrán, synchronizing with the termination of the epoch-making, two-month period associated with the Birth of His Revelation, unsurpassed, with the sole exception of the Declaration of His mission, by any episode in the world's spiritual history, call upon Bahá'í communities, East and West, to ponder the unique significance, focus attention on imperative requirements and to respond worthily to the challenge offered each of the four fate-laden, fast-approaching Intercontinental Conferences, constituting the highlights of recently ushered-in Holy Year.
Desire to announce the appointment of the Hands of the Cause, honored by direct association with the newly-initiated enterprises at the world center of the Faith, to act, in addition to their individual participation in the deliberations at the forthcoming Conferences, as my special representatives, entrusted with a four-fold mission: to bear, for the edification of the attendants, a precious remembrance of the Co-founder of the Faith, deliver my official message to the assembled believers, elucidate the character and purposes of the impending decade-long spiritual World Crusade and rally the participants to energetic, sustained, enthusiastic prosecution of the colossal tasks ahead.
Instructing the President of the International Bahá'í Council, Mason Remey, Member at Large, Ugo Giachery, and Secretary-General, Leroy Ioas, to discharge these functions in the course of the New Delhi, Stockholm and Kampala Conferences, respectively.
Delegating Amatu'l-Baha, accompanied by Vice-President of the International Council, Amelia Collins, to fulfil three of the above mentioned functions, as well as carry on my behalf, to unveil on the occasion of the completion of the construction of the Mother Temple of the West, to the privileged attendants at the Wilmette Conference a most prized remembrance of the Author of the Faith, which never before left the shores of the Holy Land, to be placed beneath the dome of the consecrated edifice. Moreover assigning her the task to act as my deputy at the historic ceremony marking the official Dedication of the holiest Mashriqu'l-Adhkár of the Bahá'í world reared to the everlasting glory and honor of the Most Great Name in the heart of the North American continent.
