| + | The only [[technique]] for [[accelerating]] the [[natural]] trend of [[social]] [[evolution]] is that of applying ''spiritual pressure'' from above, thus augmenting [[moral]] [[insight]] while enhancing the [[soul]] capacity of every [[mortal]] to [[understand]] and [[love]] every other mortal. [[Mutual]] understanding and fraternal [[love]] are [[transcendent]] civilizers and mighty [[factors]] in the world-wide [[realization]] of the brotherhood of man.[https://nordan.daynal.org/wiki/index.php?title=52:6_Urantia%27s_Post-Bestowal_Age (52:6.7)] |
