Besides the sufferings, which refine feeling, the development of intelligence will thus be one aspect of "the one thing needful" in the liberation of terrestrial mankind from the animal kingdom or darkness. And it is accordingly the result of this development that today appears as identical to science. When feeling becomes sufficiently refined through suffering, and when science creates analyses of this refinement, then the eternal commandment or the fulfilment of the law "Love one another" becomes a fact for terrestrial mankind. Then mankind is no longer ruled by lower instincts and primitive intelligence, but rules the world by virtue of "the holy spirit", which at that time will be an all-outshining factor in the daily life of the zones of the earth.
