the nature of all manifestation

No doubt, striving for the improvement of the world is a most praiseworthy occupation. Done selflessly, it clarifies the mind and purifies the heart. But soon man will realize that he pursues a mirage. Local and temporary improvement is always possible and was achieved again and again under the influence of a great king or teacher; but it would soon come to an end, leaving humanity in a new cycle of misery. It is in the nature of all manifestation that the good and the bad follow each other and in equal measure. The true refuge is only in the unmanifested.
