I once heard the pianist, Arthur Rubinstein, being interviewed. At one point he was asked to share his experience of playing Chopin's Nocturnes. He said in effect, "I do not know what it is. But over and over again I have had the experience of sitting in a crowded concert hall playing the Nocturnes and I can feel everyone in the room waiting for the next note." In this moment of waiting, all present find their contemplative community in their oneness with one another in the boundless mystery that enraptures them.
The goal of singing a song is not to reach the end as quickly as possible. It is a state of creating harmony, beauty, growth and understanding. The goal of work, as a sacred art, is to use the need for a product or service to develop the greatest possible power on the object, and the users. Sacred work puts the mind on service to the heart as well.
