But we may ask, the inner presence of what? Many will say, "We know we are unhappy sometimes in spite of wealth, comfort, happiness, friends, or beloved." But perhaps they will not believe that it is another lack, the lack of a divine ideal, that makes them unhappy. Others consider that life requires scope for progress, and that it is the lack of scope that causes the greatest unhappiness. Such persons think that they cannot prosper in the work that they are doing, that they cannot be any better off than the others. Such a thought is worse than death. Life is unlimited, and it wants scope to expand and rise. Without that scope life is unhappy. One finds this not only among human beings, but also in nature. Look at the constant progress of sun and moon, rising and reaching the summit, the zenith, and then setting. See the rising of the crescent, and how it progresses till it becomes a full moon. That means there is scope between the crescent and the full moon. This progress is the only thing that gives happiness or pleasure or joy in life; its absence means nothing but death.
