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’)
