Where, then, does happiness lie? In forgetfulness, not indulgence, of the self. In escape from sensual appetites, not in their satisfaction. We live in a dark, self-enclosed prison, which is all we see or know if our glance is fixed ever downward. To lift it upward, becoming aware of the wide, luminous universe outside - this alone is happiness. At its highest level, such happiness is the ecstasy that mystics have inadequately described. At more humdrum levels, it is human love; the delights and beauties of our dear earth, its colors and shapes and sounds; the enchantment of understanding and laughing, and all other exercise of such faculties as we possess; the marvel of the meaning of everything, fitfully glimpsed, inadequately expounded, but ever present.
