They who recite the verses
of the All-Merciful in the most melodious of tones will perceive in them that
with which the sovereignty of earth and heaven can never be compared. From them
they will inhale the divine fragrance of My worlds — worlds which today none
can discern save those who have been endowed with vision through this sublime,
this beauteous Revelation. Say: These verses draw hearts that are pure unto
those spiritual worlds that can neither be expressed in words nor intimated by
allusion. Blessed be those who hearken.
(Baha’u’llah, ‘The Kitab-i-Aqdas’)
