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.
Sit in meditation, but do not think. Look only at your mind. You will see thoughts coming into it. Before they can enter, throw these away from your mind until your mind is capable of entire silence.
