… God is, in His Essence, holy above ascent and descent,
entrance and exit; He hath through all eternity been free of the attributes of
human creatures, and ever will remain so. No man hath ever known Him; no soul
hath ever found the pathway to His Being. Every mystic knower hath wandered far
astray in the valley of the knowledge of Him; every saint hath lost his way in
seeking to comprehend His Essence. Sanctified is He above the understanding of
the wise; exalted is He above the knowledge of the knowing! The way is barred
and to seek it is impiety; His proof is His signs; His being is His evidence. [Sermon
by Imam ‘Alí] (Baha’u’llah, ‘The Seven Valleys’)
