The institution of Hazíratu'l-Quds -- “the Sacred Fold”

… the institution of the Hazíratu'l-Quds—the seat of the Bahá'í National Assembly and pivot of all Bahá'í administrative activity in future—must rank as one of the most important. Originating first in Persia, now universally known by its official and distinctive title signifying “the Sacred Fold,” ... this institution, still in the early stages of its development, has already lent its share to the consolidation of the internal functions of the organic Bahá'í community, and provided a further visible evidence of its steady growth and rising power. Complementary in its functions to those of the Mashriqu'l-Adhkár—an edifice exclusively reserved for Bahá'í worship—this institution, whether local or national, will, as its component parts, such as the Secretariat, the Treasury, the Archives, the Library, the Publishing Office, the Assembly Hall, the Council Chamber, the Pilgrims' Hostel, are brought together and made jointly to operate in one spot, be increasingly regarded as the focus of all Bahá'í administrative activity, and symbolize, in a befitting manner, the ideal of service animating the Bahá'í community in its relation alike to the Faith and to mankind in general.
