"Strike up such a melody and tune as to cause the nightingales of divine mysteries to be filled with joy and ecstasy... play and sing out the holy words of God with wondrous tones in the gatherings of the friends, that the listener may be freed from chains of care and sorrow, and his soul may leap for joy and humble itself in prayer to the realm of Glory... And then, with flying flags, and to the beat of drums, let us pass into the realm of the All-Glorious, and join the company on high." (Abdu'l-Bahá)
