Chapter II - Future Joys and Sorrows
985. When a spirit reincarnates in a more advanced world, is this a reward?
“It is a consequence of its purification. As spirits become purified, they reincarnate in progressively higher worlds, until having rid themselves of all materiality, wash away all impurities, and entering the eternal happiness of fully purified spirits in God’s heart.”
In worlds where the conditions of existence are less material than ours, the wants of their inhabitants are less crude and their physical suffering is less acute. The people from those worlds no longer possess the vile passions that make them each other’s enemies in lower worlds. Having no motives for hatred or jealousy, they live in peace because they practice the law of justice, love and charity and experience none of the worries and anxieties incited by envy, pride and selfishness that torment us on Earth. (See Q172, 182)
