Joy has no cost. Joy is free,unrestrained passion. Joy is a net of love by which you can catch souls....A joyful heart is the inevitable result of a heart burning with love. One imagines joy as a flame.Like all flames it needs oxygen,some life force,a combustible material,a significant activity,and then the white heat of profound effort or activity leading ultimately to inner satisfaction,if not ebullience.Happiness is a how,not a what,a talent,not an object.
