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

October 30

O concourse of the seen and the unseen! Rejoice with exceeding gladness in your hearts and souls, for the night hath come for the harvesting of the ages and the gathering up of past cycles, the night wherein all days and nights were called into being and the time preordained for this Revelation was fulfilled at the behest of Him Who is the Lord of might and power. All joy to the Concourse on high at the appearance of so glorious, so wondrous a Spirit!

This is the night [Birth of Baha’u’llah] wherein the doors of Paradise were flung open and the gates of Hell were shut fast, the night wherein the paradise of the All-Merciful was unveiled in the midmost heart of creation, the breezes of God were wafted from the retreats of forgiveness, and the Last Hour ushered in through the power of truth, could ye but know it. All joy to this night through which all days have been suffused with light, though none can apprehend this save those that are endued with certitude and discernment! 
- Baha’u’llah  (‘Tablet of the Birth, ‘Days of Remembrance’)
