Another important quality is the “yea saying” sense. This can be developed in one who in all things has an eye for the good, beautiful, and purposeful aspects of life, and not, primarily, for the blameworthy, ugly and contradictory. In Persian poetry there is a beautiful legend about Christ, which illustrates the meaning of this quality. A dead dog is lying on the road. Among the passersby is Christ. All the others turn away from the ugly sight; only Christ pauses and speaks admiringly of the animal’s beautiful teeth. It is possible to look at things in this way, and he who earnestly seeks for it may find in all things, even the most repulsive, something worthy of acknowledgment. The fruitfulness in things is not in what is lacking in them, but in what they have.
