“Recite ye the verses of God every morn and eventide.” (Bahá’u’lláh, ‘The Kitáb-i-Aqdas’)

May 19

O Monk of the Divine Unity! Ring out the bell, for the Day of the Lord is come and the Beauty of the All-Glorious hath ascended His blessed and resplendent throne. Praise be to Thee, O Thou Who art “He”, O Thou besides Whom there is none but “He”! [1]

O Húd, Prophet of the Divine Decree! Sound the clarion in the name of God, the All-Glorious, the Most Bountiful, for the Temple of holiness hath been established upon the seat of supernal glory. Praise be to Thee, O Thou Who art “He”, O Thou besides Whom there is none but “He”!

O Countenance of immortality! Pluck with the fingers of the spirit the sacred and wondrous strings, for the Beauty of the Divine Essence hath appeared, arrayed in a silken vesture of light. Praise be to Thee, O Thou Who art “He”, O Thou besides Whom there is none but “He”! 
(Baha’u’llah, ‘Days of Remembrance’)
[1] In the Tafsír-i-Hú Bahá’u’lláh explains that the name “He” (or Huva, consisting of the letters Há’ and Váv) is God’s Most Great Name, for it is a mirror in which all of God’s names and attributes are reflected together.
