Then you discover what kind of wisdom has accompanied it. The grass is greener; bird songs are sweeter; the shortcomings of your friends are more understandable and more forgivable. Happiness is like a pair of eyeglasses correcting your spiritual vision.
Nor are the insights of happiness limited to what is near around you. Unhappy, with your thoughts turned in upon your emotional woes, your vision is cut short as though by a wall. Happy, the wall crumbles.
The long vista is there for the seeing. The ground at your feet, the world about you----people, thoughts, emotions, pressures---are now fitted into the larger scene. Everything assumes a fairer proportion. And here is the beginning of wisdom.
