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

December 13

O proud ones of the earth!  Do ye believe yourselves to be abiding in palaces whilst He Who is the King of Revelation resideth in the most desolate of abodes?  Nay, by My life!  In tombs do ye dwell, could ye but perceive it.  Verily, he who faileth, in these days, to be stirred by the breeze of God is accounted among the dead in the sight of Him Who is the Lord of all names and attributes.  Arise, then, from the tombs of self and desire and turn unto the Kingdom of God, the Possessor of the Throne on high and of earth below, that ye may behold that which ye were promised aforetime by your Lord, the All-Knowing. 
- Baha'u'llah  (Tablet to Czar Alexander II, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)
