"As you sow, so shall you reap" is an old and true saying. It points out the law of cause and effect which forms one of the fundamental laws of the Universe."

Karma Yoga is the path of detached action and selfless service. At this point, you may ask, how could action be detached if a goal or mission is to be accomplished!

Now, the secret of right activity is to do the action with full dedication and enthusiasm in the correct manner and mode of operation but you need not anticipate or be anxious about the consequences or result of this action.

The actions are important but not the results thereof. The actions have to be undertaken and the duty lies in performing not just the actions, but performing it well, with complete understanding and control and dedication for the good of all concerned but not desiring to enjoy the results accruing from it. Here lies the key to Karma Yoga!
It is ‘detached’ activity.

If you are a Karma Yogi, the activities of life are simply a God given activity to serve Him. A Karma Yogi keeps on working irrespective of results and does his work with ‘detached involvement‘ as explained above.
