A joy that is shared suggests a group of friends playing, or a carefree young girl singing to herself while engaged in her work. Happiness is rising within, and spreading out into the world!
Joy comes into the world through gentle means, but springs from a solid inner base. The power of pure joy should not be underestimated. The enjoyment of learning and discovery, for example, has been the source of much progress. Accordingly, that which brings joy into the world is a source of considerable power.
If happiness is supported by personal stability, it will in time wear down the stiffest barrier and win over the hardest heart. True joy is a beacon in the world, and though it is, indeed, rare, its presence is an indication of great good fortune, both now and in the future. How could it be otherwise?
