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

September 19

Regard thou the one true God as One Who is apart from, and immeasurably exalted above, all created things. The whole universe reflecteth His glory, while He is Himself independent of, and transcendeth His creatures. This is the true meaning of Divine unity. He Who is the Eternal Truth is the one Power Who exerciseth undisputed sovereignty over the world of being, Whose image is reflected in the mirror of the entire creation. All existence is dependent upon Him, and from Him is derived the source of the sustenance of all things. This is what is meant by Divine unity; this is its fundamental principle. 
- Baha’u’llah  (‘Gleanings from the Writings of Baha’u’llah’)
