The Art of Music, the Food of the Soul and Spirit

The art of music is divine and effective. It is the food of the soul and spirit. Through the power and charm of music the spirit of man is uplifted. It has wonderful sway and effect in the hearts of children, for their hearts are pure, and melodies have great influence in them. The latent talents with which the hearts of these children are endowed will find expression through the medium of music. Therefore, you must exert yourselves to make them proficient; teach them to sing with excellence and effect. It is incumbent upon each child to know something of music, for without knowledge of this art the melodies of instrument and voice cannot be rightly enjoyed. Likewise, it is necessary that the schools teach it in order that the souls and hearts of the pupils may become vivified and exhilarated and their lives be brightened with enjoyment.

Exercise moderation in all things

It is incumbent upon them who are in authority to exercise moderation in all things. Whatsoever passeth beyond the limits of moderation will cease to exert a beneficial influence. Consider for instance such things as liberty, civilization and the like. However much men of understanding may favourably regard them, they will, if carried to excess, exercise a pernicious influence upon men.

Baha'u'llah, Tablets of Baha'u'llah, p. 169

The things that will make of you signs of guidance unto all mankind...

It is incumbent upon you to ponder in your hearts and meditate upon His words, and humbly to call upon Him, and to put away self in His heavenly Cause. These are the things that will make of you signs of guidance unto all mankind, and brilliant stars shining down from the all-highest horizon, and towering trees in the Abha Paradise.
