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

May 15

Arise thou to serve the Cause and say: I swear by the righteousness of God! Verily this is the Primal Point, arrayed in His new attire and manifested in His glorious Name. He at present beholdeth everything from this Horizon. Indeed He is supreme over all things. Amongst the Concourse on High He is known as the Most Great Announcement and in the Realms of Eternity as the Ancient Beauty, and before the Throne by this Name [1] which hath caused the footsteps of them that are endued with understanding to slip. 
- Baha’u’llah  (‘Tablets of Baha’u’llah revealed after the Kitab-i-Aqdas’)
[1] The Most Great Name
