Efficiency and dexterity in action means acting fast with precision and perfect technique. There is very little waste of time, energy or resources. Also, we do the action in the spirit of Karma Yoga and build ourselves up. When we are present and single-pointed in our action, our mind is less cluttered and detached from the results. In a silent and purified mind, we can feel grace and divinity working through us. This inspires us to focus more on our spiritual growth, taking us closer to our ultimate goal.
