Verily We have sounded the Trumpet which is none other than My Pen of Glory, and lo, mankind hath swooned away before it, save them whom God pleaseth to deliver as a token of His grace. He is the Lord of bounty, the Ancient of Days. 
(Baha’u’llah, ‘Tablets of Baha’u’llah revealed after the Kitab-i-Aqdas’)
