As suggested by Berit
"we could open a new topic on the Heavenforum and we could in just one sentence say what Heavenletters are for us, what they mean to us, and maybe you could pubblish that ?" - Berit from Italy
In the movie, La Bella Verte (The Green Beautiful) the people from another planet zap Earth people with a telepathic power they have that "unplugs" Earth people from "the system". Zapped people step out of their routine and start to see the beauty of the world.
Reading a Heavenletter is like a guaranteed zapping.
