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.
To be in service to God is to realize that there is a loving force in the universe, and I must pull away the veil and allow the force to come through.
