September 3

In brief, there are three realities in man. One is the animal reality, which represents the world of nature, and which is subject to disintegration. The second is the human reality, which reality is everlasting. If it rescues itself from the baser nature, it will constantly progress and will become a radiant spirit, because the divine virtues possible of attainment in the human world are unlimited. Therefore there is no end to the development of humanity. Progress is interminable. Confirmation is everlasting.
