Peterson on song and dance

"Song and dance are the result of an excess of energy.  When we are normal we talk, when we are dying we whisper, but when there is more in us than we can contain we sing.  When we are healthy we walk, when we are decrepit we shuffle, but when we are beyond ourselves with vitality we dance."

     Eugene H. Peterson, "Unself-made," Earth & altar:  the community of prayer in a self-bound society (New York:  Paulist Press, 1985), 36.  I have not read the book as a whole, but stumbled upon this when searching it for something else.
