Man has three aspects. These have been interpreted according to former terminology as three molds.
One is the animal mold, which is also known as the reality of darkness, -- that is, a reality emanating from the world of nature, -- and in that reality man has faculties and powers in common with the animal.
The second mold is the human reality, sometimes termed the astral reality. It is the mold between darkness and light, in which the soul is able to choose whether it will acquire all the virtues or remain subject to all vices.
The third mold is the spiritual reality, which is light itself.
When man remains in the animal mold, or lingers in the world of nature, he becomes utterly bereft of the light, inasmuch as the world of nature is one of darkness. But when he progresses from the animal mold he enters the human reality, or the stage between darkness and light. From one aspect the human reality is connected with the world of darkness, and from the other aspect it is connected with the world of light, which is represented in man by the third, or spiritual, reality. This third mold comprises the spiritual virtues, and is symbolized by the world of angels….
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.
