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.
We attract angels by becoming the qualities that are of interest to them. When we focus on such qualities as compassion, faith or tolerance . . . we attract angelic beings that are trying to help develop that in all humanity.
