The Mashriqu’l-Adhkar (the Baha’i Temple) in Chicago “marks the inception of the Kingdom of God on earth."

"A most wonderful and thrilling motion will appear in the world of existence," are 'Abdu'l-Bahá's own words, predicting the release of spiritual forces that must accompany the completion of this most hallowed House of Worship. "From that point of light," He, further glorifying that edifice, has written, "the spirit of teaching ... will permeate to all parts of the world." And again: "Out of this Mashriqu'l-Adhkar, without doubt, thousands of Mashriqu'l-Adhkars will be born." "It marks the inception of the Kingdom of God on earth."
