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

August 31

O King!... This [Baha'u'llah] is but a leaf which the winds of the will of thy Lord, the Almighty, the All-Praised, have stirred. Can it be still when the tempestuous winds are blowing?  Nay, by Him Who is the Lord of all Names and Attributes! They move it as they list. The evanescent is as nothing before Him Who is the Ever-Abiding. His all-compelling summons hath reached Me, and caused Me to speak His praise amidst all people. 
- Baha'u'llah  (Tablet to Nasiri’d-Din Shah, Suriy-i-Haykal [Tablet of Temple]; ‘The Summons of the Lord of Hosts’)
