August 17

Take heed lest ye hesitate in recognizing this resplendent Beauty when once He hath appeared in the plenitude of His sovereign might and majesty.  He, verily, is the True One, and all else besides Him is as naught before a single one of His servants, and paleth into nothingness when brought face to face with the revelation of His splendours.  Hasten, then, to attain the living waters of His grace, and be not of the negligent.  As to him who hesitateth, though it be for less than a moment, God shall verily bring his works to naught and return him to the seat of wrath; wretched indeed is the abode of them that tarry! 
- Baha'u'llah  (Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)
