"You know about the special musical instruments that are in Our possession. Urusvati has heard them. The refined scale and rhythm of Sister Oriole should be acknowledged as the highest harmony. Often such singing has served to bring peace to the world... One should learn how to develop one’s own musicality by all possible means. The heart’s feeling is sensed not in the words themselves but in their sound. There can be no irritation in harmony. Malice cannot exist where the spirit ascends. It is not by chance that in antiquity the epic scriptures were sung, not only to facilitate memorizing but also for inspiration. Likewise, it is rhythm and harmony that protect us against fatigue. The quality of music and rhythm should be developed from infancy."
