All the days have been honoured, O my God, by the arrival of the days upon which Thou hast conferred the name of Há, each of which Thou hast made a herald and a messenger announcing unto the people the advent of the days on which Thou didst enjoin Thy creation and Thy people to observe the Fast. Thus may every soul prepare himself to behold these days and appoint a place for them in his heart and purify it by Thy Name, the Lord, for their appearance.

—Bahá’u’lláh
