Verily I say! No one hath apprehended the root of this
Cause. It is incumbent upon everyone, in this day, to perceive with the eye of
God, and to hearken with His ear. Whoso beholdeth Me with an eye besides Mine
own will never be able to know Me. None among the Manifestations of old, except
to a prescribed degree, hath ever completely apprehended the nature of this
Revelation.
- Baha’u’llah (Quoted by Shoghi Effendi in ‘The Advent of Divine
Justice’)
