May 3

Lift up the veils and coverings that obscure your vision, and consider the testimonies of the Prophets and Messengers, that haply ye may recognize the Cause of God in these days when the Promised One hath come invested with a mighty sovereignty.  Fear God, and debar yourselves not from Him Who is the Dayspring of His signs.  This shall, in truth, but profit your own selves; as to your Lord, He, verily, can afford to dispense with all creatures.  From everlasting was He alone; there was none else besides Him.  He it is in Whose name the standard of Divine Unity hath been planted upon the Sinai of the visible and invisible worlds, proclaiming that there is none other God but Me, the Peerless, the Glorious, the Incomparable. 
- Baha'u'llah  (‘Suriy-i-Haykal, ‘The Summons of the Lord of Hosts’)
