August 26

In all the Divine Books the promise of the Divine Presence hath been explicitly recorded. By this Presence is meant the Presence of Him Who is the Dayspring of the signs, and the Dawning-Place of the clear tokens, and the Manifestation of the Excellent Names, and the Source of the attributes, of the true God, exalted be His glory. God in His Essence and in His own Self hath ever been unseen, inaccessible, and unknowable. By Presence, therefore, is meant the Presence of the One Who is His Vicegerent amongst men. 
- Baha’u’llah  (‘Epistle to the Son of the Wolf’)
