Action and In-action

What is action and what is inaction? This question has confused the greatest sages. I will give you the secret of the action, with which you can free yourself from bondage. The true nature of action is difficult to grasp. You must understand what is action and what is inaction, and what kind of action should be avoided.

The wise see that there is action in the midst of inaction and inaction in the midst of action. Their consciousness is unified, and every act is done with complete awareness.

-Bhagavad Gita 4:16-17
