The most important characteristic of this devachanic world (heaven) is that in it moral actualities are no longer separable from the physical, that moral and physical laws are one and the same. What does that mean? Well, is it not true that in the ordinary physical world the sun shines upon the just and the unjust? Whoever commits a crime may be put in prison, but the physical sun is not darkened. That is to say: in the physical world there is a realm of moral and physical laws, leading in two very different directions.
It is not so in Devachan, not at all; instead of this, everything proceeding from morality, from intelligent wisdom, from the aesthetically beautiful, and so on, leads to growth (is creative,) and that which arises from immorality, intellectual falsity, and aesthetic ugliness leads to withering and destruction. And there the laws of nature are such that the sun does not shine upon the just and the unjust alike but, if we may speak figuratively, it darkens upon the unjust; so that the just, passing through Devachan, have there the spiritual sunshine, that is to say, the influence of the fertilizing forces that bring about their forward progress in life.
The spiritual forces draw back from the dishonest or ugly human being. The following is possible there which is impossible here on earth. When two people — just and unjust — walk here side by side, the sun cannot shine upon one and not upon the other; but in the spiritual world the effect of the spiritual forces depends absolutely upon the quality of the individual concerned. That is to say: the laws of nature and the spiritual laws do not follow two separate roads, but one and the same. That is the fundamental, essential truth. In the devachanic world the natural, moral, and intellectual laws act together as one.
