Three years before his passing, Shoghi Effendi took advantage of the acquisition of the last plot of land needed for the erection of the International Archives Building to describe for the Bahá’í world the nature and significance of the building project on the slopes of Mount Carmel that the Master had inaugurated and that he himself was pursuing: These Edifices will, in the shape of a far-flung arc, and following a harmonizing style of architecture, surround the resting-places of the Greatest Holy Leaf ... of her Brother ... and of their Mother.... The ultimate completion of this stupendous undertaking will mark the culmination of the development of a world-wide divinely-appointed Administrative Order whose beginnings may be traced as far back as the concluding years of the Heroic Age of the Faith.(157) The current stage of this ambitious enterprise was brought to its successful conclusion in the final year of the century. An outpouring of resources from believers throughout the world had responded to the vision of Bahá’u’lláh for this sacred spot, announced in His Tablet of Carmel: “Rejoice, for God hath in this day established upon thee His throne, hath made thee the dawning-place of His signs and the dayspring of the evidences of His Revelation.” In the complex of majestic buildings spread out along the Arc and the flights of terraced gardens rising from the foot of the mountain to its summit, the Cause whose influence had steadily expanded throughout the world during the century of light emerged finally as a visible and compelling presence. In the crowds of visitors from every land thronging the stairs and pathways each day and the stream of distinguished guests who are welcomed to the World Centre’s reception rooms, perceptive minds already sense the dawning fulfilment of the vision recorded twenty-three hundred years ago by the prophet Isaiah: “And it shall come to pass in the last days, _that_ the mountain of the Lord’s house shall be established in the top of the mountains, and shall be exalted above the hills; and all nations shall flow unto it.”(158)
