Music consists of tones of varying frequencies sounded one after another. A song results from the differences of one in relation to the other, be it in pitch or tempo. If there were no difference in either, you would have no song, simply one sound. Sound is good, but not as enjoyable as a song. Imagine if all those around you were exactly the same. What an uninteresting song you would all play. Of course, with the differences in all of you, there oft results dissonance instead of harmony. You feel this as discomfort, for natural law causes all to desire resonance.
Love harmonizes all. Sing a love song today. Seek harmony in your thoughts and actions. In so doing, you bring those around you into tune. What a beautiful tune you will play when all sing of love in spite of your differences.
