BHAGAVAD GITA, pt. 7: Karma Yoga - A Methodical Approach to Freedom

Chapter 2, v. 39-40;

Karma Yoga is not just a path of action, even if that action is doing good works. Karma Yoga is a path of discernment that gives us a reorientation about how we do what we do and what the purpose is of what we're doing. Turning our attention and our awareness around is a change from seeking the results of action to doing what we do as an offering to God.
