According to the philosophy of GNH, happiness is a natural instinct that can be achieved through mental and physical satisfaction within a peaceful and sustainable environment. GNH does not necessarily contradict economic growth. Economic growth is just one way to achieve the ultimate goal of national happiness. Rather than blindly promoting economic growth, it is important to achieve economic growth that enables citizens to be good in heart and mind while balancing development and environmental conservation. During his visit to Japan in 2011, after the Great East Japan Earthquake, His Majesty Jigme Khesar Namgyel Wangchuck, the Fifth King of Bhutan and the first son of the Fourth King, said, "GNH functions as a bridge between the need for economic growth and our basic values such as gentleness, fairness, and humanity." These words express the GNH philosophy well.
