Selection from Arcana Coelestia ~ Emanuel Swedenborg
The man who has been alienated from good and truth intends nothing but evil, because he cannot intend good; and what he intends, reigns with him, and therefore is in all his thoughts, and in every least detail of him; for the intention or end is the veriest life of man, the end being his love, and the love being his life. And what is more, a man is exactly such as is the end with him, and such also is his image in the light of heaven; and — this may surprise you — such as is his image in general, such is the image of the least things of his will. Thus the whole man is such as his end is.
From this it is evident that the man who is an evil end cannot possibly be among those who are good ends; thus he who is in hell cannot possibly be in heaven; for the ends conflict, and the good ends prevail, because they are from the Divine. Hence also it is evident that they do not think truly who believe that everyone can be admitted into heaven from mercy alone; for if one who is an evil end comes into heaven, his life labors as with one who lies in the death agony, and he is direfully tortured; besides that in the light of heaven he appears as a devil. Hence it is evident that they who have been alienated from truth and good can think nothing but evil; and that this evil is in the least things of their thought and will is very manifest from the sphere which from afar exhales from such spirits, for their quality is thereby perceived. This sphere is like a spiritual evaporation from every detail of the life.
