The chief characteristic of Devachan is that moral facts can no longer be distinguished from physical facts, or physical laws; moral laws and physical laws coincide. What is meant by this? In the ordinary physical world the sun shines over the just and the unjust; one who has committed a crime may perhaps be put in prison, but the physical sun will not be darker because of this fact. This signifies that the world of sense-reality has both a moral order of laws and physical one; but they follow two entirely different directions. In Devachan it is otherwise — there, this difference does not exist at all. In Devachan everything that arises out of something moral, or intellectually wise, or esthetically beautiful, etc., leads to a creation, is creative — whereas everything that arises out of something immoral, intellectually untrue, or esthetically ugly, leads to destruction, is destructive.
The laws of Nature in Devachan are indeed of such kind that the sun does not shine equally brightly over the just and the unjust. Speaking figuratively, we may say that the sun actually is darkened in the case of an unrighteous man, whereas the righteous man who passes through Devachan really finds in it the spiritual sunshine, that is, the influence of the life-spending forces which help him forward in life. A liar or an ugly-minded man will pass through Devachan in such a way that the spiritual forces withdraw from him. In Devachan an order of laws is possible, which is not possible here or earth. When two people, a righteous and an unrighteous one, walk side by side here on the earth, it is not possible for the sun to shine upon one and not to shine upon the other. But in the spiritual world the influence of the spiritual forces undoubtedly depends upon the quality of a human being. In Devachan this signifies that the laws of Nature and the spiritual laws do not follow separate directions, but the same direction. This is the essential thing which must be borne in mind — in Devachan the laws of Nature and the moral and intellectual laws coincide.
