We all learn the skills to do things. But they only bind us, fetter us to karmic consequences. We are more focused on the results than the perfection of actions. Like other skills the skill for karma yoga also needs to be learned. Karma yoga teaches you how you can do what you do with utmost sincerity and dedication, love and surrender. Thus you are freed from the bondage of karmic consequences.  Karma yoga is the skill to unfetter and be free!
