But work without any selfish motive is good. It does not create any worry. But it is very difficult to be totally unselfish. We may think that our work is selfless, but selfishness comes, unknown to us, from no one knows where. But if a man has already undergone great spiritual discipline, then as a result of it he may be able to do work without any selfish motive. After the vision of God a man can easily do unselfish work. In most cases action drops away after the attainment of God.
