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.
Silence is really vital for the human heart. You see, the human heart can't live with constant sound or noise. It needs silence in order to heal itself. The only two things that are ultimately required for spiritual homecoming are stillness and silence. If, into your day, you can build little windows of silence and little windows of stillness, you will never lose touch with your deepest voice. You will never lose touch with your most secret belonging. Even though you walk and talk and act in the world, you will never leave the inner, tender home of your own soul.
