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’; The Compilation of Compilations, vol. III, The Importance of Arts in Promoting the Faith)
