on this day a hundred and fifty-two years ago–April 29, 1863–the ninth day of Baha’u’llah’s sojourn in the Garden of Ridvan (Paradise), the flooding Tigris receded enough so that Baha’u’llah’s family could cross the river and join him in the Garden. This reunification of Baha’u’llah’s family, and by extension the unity of the entire human family the Baha’i Faith calls for, permeates the symbolic meaning of the 9th day of Ridvan.
